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?
We are examining whether experimentally providing individuals (under the guise of a cover story) with information suggesting that women and minorities are frequently overlooked in favor of equally meritorious men and whites will lead individuals to favor amplifying female and minority voices.

3) Describe the key dependent variable(s) specifying how they will be measured.
We will ask individuals to play the role of a university's Director of External Communications. They will be asked to select one of several candidate faculty members to connect to a prominent media source who is looking for an expert to interview on air. We will vary the demographic characteristics of the faculty members (with two white men and one minority female). Our main dependent variable is individuals' probability of selecting the minority female faculty member as a function of condition.

4) How many and which conditions will participants be assigned to?
Participants will be assigned to one of two conditions: An experimental condition in which they read an article detailing how females and minorities are disadvantaged relative to equally meritorious whites and men, and a control condition in which they read about a neutral scientific discovery.

5) Specify exactly which analyses you will conduct to examine the main question/hypothesis.
Our main test will be a chi-square test with condition as the column in a cross-tabs and the likelihood of selecting the minority female (coded 0/1) in the row.

6) Describe exactly how outliers will be defined and handled, and your precise rule(s) for excluding observations.
We do not have any plans to exclude observations.

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.

We will collect data from 800 participants, attempting to collect data from approximately equal numbers of Democrats and Republicans (inclusive of independents who 'lean' Democrat or Republican).

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

As a secondary analysis, we will examine whether the effect of condition on the likelihood of selecting the minority female is moderated by political party membership, reasoning that the effect of condition may be stronger among Democrats.
As an exploratory analysis, we will examine the effect of condition on continuous ratings of the likelihood of connecting the minority female to the media producer (as compared to our main, dichotomous DV).
