Frequently Asked Questions

A guilt trip means causing another person to feel guilt or a sense of responsibility to change their behavior or take a specific action. Because guilt can be such a powerful motivator of human behavior, people can wield it as a tool to change how others think, feel, and behave. 

Sometimes this might involve leaning on something that someone already feels guilty about. In other cases, people might induce feelings of unjustified guilt or responsibility to manipulate the other person's emotions and behaviors.

If someone has ever made you feel bad about something you’ve done (or didn’t do) and then used those bad feelings to get you to do something for them, then you have experience with guilt tripping.

This article discusses the signs, types, and impact of guilt trips. It also covers some of the steps you can take to cope with this type of behavior.

Signs of a Guilt Trip

Guilt trips can be intentional, but they can also be unintentional. There are chances that you have even guilt-tripped people into doing things before.

Sometimes guilt tripping behavior can be easy to spot, but it can also be much more subtle and difficult to detect.  Some key signs that others may be guilt-tripping you include:

• Making comments suggesting that you have not done as much work as they have done
• Bringing up mistakes that you have made in the past
• Reminding you of favors they have performed for you in the past
• Acting as if they are angry but then denying that there is a problem
• Refusing to speak to you or giving you the silent treatment
• Making it clear through their body language , tone of voice, and facial expressions that they disapprove of what you were doing
• Suggesting that you “owe” them
• Engaging in passive-aggressive behavior
• Making sarcastic comments about your efforts or progress

It is important to note that this type of indirect communication can occur in any interpersonal relationship. Still, it is more likely to take place in relationships that are marked by close emotional connections.

It can show up in romantic relationships, but guilt trips may also be utilized in family relationships, parental relationships, and even work relationships.

Types of Guilt Tripping

There are many different types of guilt trips that people may utilize depending on the ultimate goal or purpose of the behavior. Some of the different purposes of a guilt trip include:

• Manipulation : Sometimes, the primary goal of a guilt trip is to manipulate someone into doing something that they normally would not want to do.  
• Conflict avoidance : In other cases, people may use guilt trips to avoid directly talking about an issue. It allows them to get what they want without having to engage in direct conflict.
• Moral education : Guilt trips can also be a way of getting someone to engage in a behavior that the individual feels is more moral or “right.”
• Elicit sympathy : In some cases, guilt-tripping allows the individual to gain the sympathy of others by casting themselves in the role of someone who has been harmed by the actions the other person is supposed to feel guilty about.

Guilt isn't always a bad thing. While often troubling and unpleasant, it can serve an important role in guiding moral behavior. When people experience guilt, they can fix their mistakes and avoid repeating the same errors in the future.

Researcher Courtney Humeny

A guilt trip does not appear to induce the benefits of guilt, such as making amends, honesty, and mutual understanding.

Impact of Guilt Trips

Invoking feelings of guilt to change someone’s behavior can have a wide variety of effects. Whether guilt is wielded intentionally or not, it prevents healthy communication and connections with others. Some of the most immediate effects of this form of covert psychological manipulation include:

Damage to Relationships

Research suggests that guilt trips can take a toll on close relationships. One study found that people hurt by their partner's criticism were more likely to use those hurt feelings to make their partner feel guilty and offer reassurances.

However, the study also found that the partner who had been guilt-tripped into offering assurances was more likely to feel significantly worse about the relationship.

In other words, inducing feelings of guilt may work to get your partner to do what you want—but it comes at a cost. It can impair trust and cause the other person to feel that they are being manipulated. 

One of the reasons why guilt trips can poison relationships is because they can lead to lasting feelings of resentment.

"A guilt trip imposes aversive states associated with guilt, along with feelings of resentment from feeling manipulated," Humeny suggests.

A single occasion of someone using a guilt trip to alter your behavior might not have a serious impact on your relationship. Repeated use of guilt trips can leave you feeling bitter.

If you feel that your partner is always going to guilt you into something that you don't want to do, it can decrease intimacy, reduce emotional closeness, and ultimately make you start to resent your partner.

Research suggests that appeals to guilt are a common type of persuasion technique . However, while guilt can compel people to take certain actions, it can also sometimes backfire.

Low-level guilt tends to motivate people to act on the persuasive message. High levels of guilt, however, often fail due to what researchers call "reactance." 

"An individual in a state of reactance will behave in such a way as to restore his freedom (or, at least, his sense of freedom), for example, by performing behaviors that are contrary to those required," explain researchers Aurélien Graton and Melody Mailliez in a 2019 article published in the journal Behavioral Sciences .

In other words, guilt trips can backfire and lead people to behave opposite how someone else wants them to act. For example, someone guilt-tripping you into calling them more often might actually result in calling them less.

Poor Well-being

Feelings of excessive guilt are associated with several mental health conditions, including anxiety, depression , and obsessive-compulsive disorder . Being subjected to guilt trips may contribute to the development or worsening of such conditions.

Experiencing guilt can also lead to many immediate and unpleasant emotions and symptoms such as anxiety, sadness, regret, worry, muscle tension, and insomnia.

This type of covert manipulation may also sometimes contribute to the development of a guilt complex , which is a persistent belief that you have done (or will do) something wrong.

Over time, guilt can lead to feelings of shame. Shame can affect your self-image, which can then contribute to social withdrawal and isolation.

How to Cope With Guilt Tripping

There are a number of tactics that can be helpful when dealing with a guilt trip. Some steps you can take include:

• Acknowledge the request. Let them know that you understand that it is important to them. Responding with empathy and showing that you see their needs may help them feel that they are not simply being ignored. Validating their emotions may help lessen the intensity of those feelings.
• Share your feelings . Explain that you also see how they are trying to make you feel guilty so that you'll do what they want. Then tell them how that type of manipulation makes you feel. Suggest that interacting in that way will lead to resentment and that more direct communication forms would be more effective. 
• Set boundaries . Boundaries help set limits on what you will and will not accept. Even if you do end up helping them with their request, make sure you clearly articulate your limits and explain the consequences of crossing those boundaries. Then be sure that you enforce those limits if they are crossed.

Other things that you can use include protecting your self-esteem and distancing yourself if needed. You're more likely to fall for a guilt trip if you already feel poorly about yourself, so find strategies to build up your sense of self-worth. 

If the other person keeps trying to manipulate you with feelings of guilt, reduce your communication with them or even consider ending the relationship.

Protecting your own well-being should be a top priority. A person who tries to manipulate you with toxic feelings of shame and guilt does not have your best interests at heart.

Getting Help for Guilt

If you are experiencing feelings of guilt or related symptoms of anxiety, stress, or depression, talk to your health care provider or a mental health professional. They can recommend treatment options such as psychotherapy or medications that can help manage symptoms and improve the quality of your life.

Your doctor or therapist may suggest a type of therapy called cognitive-behavioral therapy (CBT) , which may help reduce inappropriate guilt feelings. This type of therapy can help you identify and change the negative thoughts and cognitive distortions that can contribute to feelings of guilt.

Your therapist can also help you learn to recognize the signs of a guilt trip—and help you practice strategies to cope with this type of emotional manipulation.

An example of guilt tripping might be your friend calling you and saying, "I know you are too busy with work to hang out. I'll just spend the evening by myself. I just thought that since I helped you get that job you would make sure to make a little more time for me." This type of comment is designed to induce feelings of guilt and bring up the idea that you "owe" them in some way.

Guilt tripping is often designed to manipulate other people by preying on their emotions and feelings of guilt or responsibility. This can be a form of toxic behavior that can have detrimental effects on a person's well-being as well as their relationships.

While both behaviors are destructive and toxic, they differ in key ways. Gaslighting is a type of emotional abuse that involves denying another person's reality and making them question their own experiences. Guilt tripping, on the other hand, is about causing another person to feel guilty in order to get them to change their behavior.

3.4: Trip Generation

• Last updated
• Save as PDF
• Page ID 47326

• David Levinson et al.
• Associate Professor (Engineering) via Wikipedia

Trip Generation is the first step in the conventional four-step transportation forecasting process (followed by Destination Choice, Mode Choice, and Route Choice), widely used for forecasting travel demands. It predicts the number of trips originating in or destined for a particular traffic analysis zone.

Every trip has two ends, and we need to know where both of them are. The first part is determining how many trips originate in a zone and the second part is how many trips are destined for a zone. Because land use can be divided into two broad category (residential and non-residential) we have models that are household based and non-household based (e.g. a function of number of jobs or retail activity).

For the residential side of things, trip generation is thought of as a function of the social and economic attributes of households (households and housing units are very similar measures, but sometimes housing units have no households, and sometimes they contain multiple households, clearly housing units are easier to measure, and those are often used instead for models, it is important to be clear which assumption you are using).

At the level of the traffic analysis zone, the language is that of land uses "producing" or attracting trips, where by assumption trips are "produced" by households and "attracted" to non-households. Production and attractions differ from origins and destinations. Trips are produced by households even when they are returning home (that is, when the household is a destination). Again it is important to be clear what assumptions you are using.

People engage in activities, these activities are the "purpose" of the trip. Major activities are home, work, shop, school, eating out, socializing, recreating, and serving passengers (picking up and dropping off). There are numerous other activities that people engage on a less than daily or even weekly basis, such as going to the doctor, banking, etc. Often less frequent categories are dropped and lumped into the catchall "Other".

Every trip has two ends, an origin and a destination. Trips are categorized by purposes , the activity undertaken at a destination location.

Observed trip making from the Twin Cities (2000-2001) Travel Behavior Inventory by Gender

Some observations:

• Men and women behave differently on average, splitting responsibilities within households, and engaging in different activities,
• Most trips are not work trips, though work trips are important because of their peaked nature (and because they tend to be longer in both distance and travel time),
• The vast majority of trips are not people going to (or from) work.

People engage in activities in sequence, and may chain their trips. In the Figure below, the trip-maker is traveling from home to work to shop to eating out and then returning home.

Specifying Models

How do we predict how many trips will be generated by a zone? The number of trips originating from or destined to a purpose in a zone are described by trip rates (a cross-classification by age or demographics is often used) or equations. First, we need to identify what we think the relevant variables are.

The total number of trips leaving or returning to homes in a zone may be described as a function of:

\[T_h = f(housing \text{ }units, household \text{ }size, age, income, accessibility, vehicle \text{ }ownership)\]

Home-End Trips are sometimes functions of:

• Housing Units
• Household Size
• Accessibility
• Vehicle Ownership
• Other Home-Based Elements

At the work-end of work trips, the number of trips generated might be a function as below:

\[T_w=f(jobs(area \text{ }of \text{ } space \text{ } by \text{ } type, occupancy \text{ } rate\]

Work-End Trips are sometimes functions of:

• Area of Workspace
• Occupancy Rate
• Other Job-Related Elements

Similarly shopping trips depend on a number of factors:

\[T_s = f(number \text{ }of \text{ }retail \text{ }workers, type \text{ }of \text{ }retail, area, location, competition)\]

Shop-End Trips are sometimes functions of:

• Number of Retail Workers
• Type of Retail Available
• Area of Retail Available
• Competition
• Other Retail-Related Elements

A forecasting activity conducted by planners or economists, such as one based on the concept of economic base analysis, provides aggregate measures of population and activity growth. Land use forecasting distributes forecast changes in activities across traffic zones.

Estimating Models

Which is more accurate: the data or the average? The problem with averages (or aggregates) is that every individual’s trip-making pattern is different.

To estimate trip generation at the home end, a cross-classification model can be used. This is basically constructing a table where the rows and columns have different attributes, and each cell in the table shows a predicted number of trips, this is generally derived directly from data.

In the example cross-classification model: The dependent variable is trips per person. The independent variables are dwelling type (single or multiple family), household size (1, 2, 3, 4, or 5+ persons per household), and person age.

The figure below shows a typical example of how trips vary by age in both single-family and multi-family residence types.

The figure below shows a moving average.

Non-home-end

The trip generation rates for both “work” and “other” trip ends can be developed using Ordinary Least Squares (OLS) regression (a statistical technique for fitting curves to minimize the sum of squared errors (the difference between predicted and actual value) relating trips to employment by type and population characteristics.

The variables used in estimating trip rates for the work-end are Employment in Offices (\(E_{off}\)), Retail (\(E_{ret}\)), and Other (\(E_{oth}\))

A typical form of the equation can be expressed as:

\[T_{D,k}=a_1E_{off,k}+a_2E_{oth,k}+a_3E_{ret,k}\]

• \(T_{D,k}\) - Person trips attracted per worker in Zone k
• \(E_{off,i}\) - office employment in the ith zone
• \(E_{oth,i}\) - other employment in the ith zone
• \(E_{ret,i}\)- retail employment in the ith zone
• \(a_1,a_2,a_3\) - model coefficients

Normalization

For each trip purpose (e.g. home to work trips), the number of trips originating at home must equal the number of trips destined for work. Two distinct models may give two results. There are several techniques for dealing with this problem. One can either assume one model is correct and adjust the other, or split the difference.

It is necessary to ensure that the total number of trip origins equals the total number of trip destinations, since each trip interchange by definition must have two trip ends.

The rates developed for the home end are assumed to be most accurate,

The basic equation for normalization:

\[T'_{D,j}=T_{D,j} \dfrac{ \displaystyle \sum{i=1}^I T_{O,i}}{\displaystyle \sum{j=1}^J T_{TD,j}}\]

Sample Problems

Planners have estimated the following models for the AM Peak Hour

\(T_{O,i}=1.5*H_i\)

\(T_{D,j}=(1.5*E_{off,j})+(1*E_{oth,j})+(0.5*E_{ret,j})\)

\(T_{O,i}\) = Person Trips Originating in Zone \(i\)

\(T_{D,j}\) = Person Trips Destined for Zone \(j\)

\(H_i\) = Number of Households in Zone \(i\)

You are also given the following data

A. What are the number of person trips originating in and destined for each city?

B. Normalize the number of person trips so that the number of person trip origins = the number of person trip destinations. Assume the model for person trip origins is more accurate.

Solution to Trip Generation Problem Part A

\[T'_{D,j}=T_{D,j} \dfrac{ \displaystyle \sum{i=1}^I T_{O,i}}{\displaystyle \sum{j=1}^J T_{TD,j}}=>T_{D,j} \dfrac{37500}{36750}=T_{D,j}*1.0204\]

Solution to Trip Generation Problem Part B

Modelers have estimated that the number of trips leaving Rivertown (\(T_O\)) is a function of the number of households (H) and the number of jobs (J), and the number of trips arriving in Marcytown (\(T_D\)) is also a function of the number of households and number of jobs.

\(T_O=1H+0.1J;R^2=0.9\)

\(T_D=0.1H+1J;R^2=0.5\)

Assuming all trips originate in Rivertown and are destined for Marcytown and:

Rivertown: 30000 H, 5000 J

Marcytown: 6000 H, 29000 J

Determine the number of trips originating in Rivertown and the number destined for Marcytown according to the model.

Which number of origins or destinations is more accurate? Why?

T_Rivertown =T_O ; T_O= 1(30000) + 0.1(5000) = 30500 trips

T_(MarcyTown)=T_D ; T_D= 0.1(6000) + 1(29000) = 29600 trips

Origins(T_{Rivertown}) because of the goodness of fit measure of the Statistical model (R^2=0.9).

Modelers have estimated that in the AM peak hour, the number of trip origins (T_O) is a function of the number of households (H) and the number of jobs (J), and the number of trip destinations (T_D) is also a function of the number of households and number of jobs.

\(T_O=1.0H+0.1J;R^2=0.9\)

Suburbia: 30000 H, 5000 J

Urbia: 6000 H, 29000 J

1) Determine the number of trips originating in and destined for Suburbia and for Urbia according to the model.

2) Does this result make sense? Normalize the result to improve its accuracy and sensibility?

• purpose (to work, return home, work related business, shopping, family/personal business, school, church, medical/dental, vacation, visit friends or relatives, other social recreational, other) (use the codes provided)
• if you traveled with anyone else, and if so whether they lived in your household or not.

Bonus: Email your professor at the end of everyday with a detailed log of your travel diary. (+5 points on the first exam)

• Are number of destinations always less than origins?
• Pose 5 hypotheses about factors that affect work, non-work trips? How do these factors affect accuracy, and thus normalization?
• What is the acceptable level of error?
• Describe one variable used in trip generation and how it affects the model.
• What is the basic equation for normalization?
• Which of these models (home-end, work-end) are assumed to be more accurate? Why is it important to normalize trip generation models
• What are the different trip purposes/types trip generation?
• Why is it difficult to know who is traveling when?
• What share of trips during peak afternoon peak periods are work to home (>50%, <50%?), why?
• What does ORIO abbreviate?
• What types of employees (ORIO) are more likely to travel from work to home in the evening peak
• What does the trip rate tell us about various parts of the population?
• What does the “T-statistic” value tell us about the trip rate estimation?
• Why might afternoon work to home trips be more or less than morning home to work trips? Why might the percent of trips be different?
• Define frequency.
• Why do individuals > 65 years of age make fewer work to home trips?
• Solve the following problem. You have the following trip generation model:

\[Trips=B_1Off+B_2Ind+B_3Ret\]

And you are given the following coefficients derived from a regression model.

If there are 600 office employees, 300 industrial employees, and 200 retail employees, how many trips are going from work to home?
