A Computer Is Required

In this study you answer by moving a slider with a mouse or a trackpad. A phone or tablet does not have one, so this device cannot be used.

Please return this study. If you would like to take part, open it again on a desktop or laptop computer.

Before You Begin

In this study, you will use a trackpad or a mouse to provide responses.

Informed Consent

Please read the consent information below before continuing. Your participation in this study is voluntary, and you may withdraw at any time without penalty.

I have read and understood the information above, and I agree to participate in this study.

To ensure data quality, it is important that your responses reflect your own judgment. The use of AI tools (such as ChatGPT) to generate or assist with your responses is not permitted, and this study uses automated methods to help detect such use.

I confirm that I will complete this study using only my own judgment, without the assistance of any AI tools.

Impression Formation Study

In this study, you will read about 3 different people, each described by a single trait. For each person, you will rate the extent to which you think they also have around 30 other traits, one at a time.

The task involves around 90 short ratings in total and should take about 12–18 minutes. You'll get a short break between people.

You answer by moving a slider on a scale from 0 to 100. The next two pages explain how, and there are 5 practice trials before the study starts.

The rating task

On each trial you will read: "The person has the trait: [Trait 1]. To what extent do you think the person is also [Trait 2]." You answer on a scale from 0 to 100.

0 — not at all. (Knowing they have Trait 1 does not at all make me think they have Trait 2.)
100 — definitely. (Knowing they have Trait 1 makes it practically certain that they have Trait 2.)
Use the middle of the scale when it is suggested somewhat.

For example, learning that someone is greedy might strongly suggest they are also selfish, so that would be a high number. It provides no evidence that they are left-handed, so that would be 0. Similarly, it provides no evidence that they are generous (in fact, it suggests the opposite), so that would also be 0.

How to answer

You will enter your responses with a mouse or a trackpad, on a slider like the one below:

1. Read the question and make up your mind about your answer;
2. Click on the slider, or drag its handle, to the point on the scale that matches your answer;
3. Click Continue to record your answer and move on to the next question.

Practice

You will start five practice trials next.

Make up your mind before you move. Take as long as you need to read each question and think about your answer, then move the slider to it and click Continue.

Practice Complete

You have completed all five practice trials. You will start the experiment next. Please remember to read each question and decide your answer before moving the slider.

In the experiment, you will rate 3 people, each on 30 trials.

Next Person

The person has the trait: .

Take a moment to form an impression of this person — think about what they may be like in general. You'll then rate them on a series of traits, one at a time.

Take a Break

You've finished rating this person. Take as long as you need — when you're ready, continue to the next person.

Final Questions
