Detailed Description of Method/Results The original authors generously provided their materials in an appendix, so we were able to run an identical version of the original study using a larger sample size.

Operationalization of efficacy: TurkPrime workers read the following message either at the beginning (high efficacy salience condition) or at the end (low efficacy salience condition) of a solicitation for donations to a particular charity: "You can take steps to make a meaningful difference. Volunteers are the backbone of our organization, and we rely on our extensive and committed network of volunteers to carry out our important work."

They were then asked a series of questions, the key dependent measures being three questions regarding their willingness to donate to the charity in question.

NZC ran the study twice (the first time unknowingly not restricting the TurkPrime sample). Results will follow for both the restricted and unrestricted samples, respectively:

-Restricted sample (minimum 91% of approved completed HITs): The three donation measures (donating money, supplies, time) were combined to form a single measure of willingness to donate (a = 0.819).

After re-running the study with sample restrictions, we were unable to replicate the results of the original study. No difference in willingness to donate was found between the high efficacy condition (M = 4.66, SD = 1.70) and the low efficacy condition (M = 4.57, SD = 1.61), F(1,383) = .274, p = .60.

-Unrestricted sample:
The three donation measures (donating money, supplies, time) were combined to form a single measure of willingness to donate (a = 0.839).

We were unable to replicate the results of the original study. No difference in willingness to donate was found between the high (M = 4.18, SD = 1.74) and the low (M = 3.91, SD = 1.90) efficacy condition, F(1,387) = 2.189, p = .14.
