(AsPredicted #4019)

This is an anonymized version of the pre-registration.  It was created by the author(s) to use during peer-review.
A non-anonymized version (containing author names) should be made available by the authors when the work it supports is made public.

1) Have any data been collected for this study already?
No, no data have been collected for this study yet

2) What's the main question being asked or hypothesis being tested in this study?
The psychological experience of air pollution increases unethical behavior, partly by increasing anxiety/stress.

3) Describe the key dependent variable(s) specifying how they will be measured.
We will measure unethical behavior using 5 items from the Self-Reported Inappropriate Negotiation Strategies Scale (SINS):
1. Try to lead the other person to believe that they can only get what they want by negotiating with you, when in fact they could go elsewhere to get what they want cheaper or faster.
2. Promise that good things will happen to your opponent if he/she gives you what you want, even if you know that you can't (or won't) deliver these things.
3. Intentionally misrepresent information to your opponent in order to strengthen your negotiating arguments or position.
4. Acquire negative personal information about your opponent and use that information to force them to give you what you want.
5. Gain information about an opponent's negotiating position by trying to recruit or hire one of your opponent's teammates (on the condition that the teammate bring confidential information with him/her).
We will measure anxiety/stress with 6 items adapted from Spielberger State-Trait Anxiety Inventory (STAI) and Kouchaki & Desai (2015):
“To what extent do you feel: calm/ tense/ upset/ relaxed/ neutral/ anxious” (1= not at all, 5= very much)

4) How many and which conditions will participants be assigned to?
Participants will be randomly assigned to 1 of 2 experimental conditions: pollution vs clean condition.

5) Specify exactly which analyses you will conduct to examine the main question/hypothesis.
An independent-samples t-test will be used to compare the mean SINS score between the two experimental conditions.

6) Any secondary analyses?
Mediation analyses will be conducted to examine whether anxiety/ stress mediates the effect of the experimental condition on SINS score.

7) How many observations will be collected or what will determine sample size?
No need to justify decision, but be precise about exactly how the number will be determined.

Based on G*Power calculation, we aim to recruit a total of 360 valid Indian participants on MTurk.

8) Anything else you would like to pre-register?
(e.g., data exclusions, variables collected for exploratory purposes, unusual analyses planned?)

If participants correctly identify the city as Beijing, they will be excluded from all analyses.
