Brief Statement of Original Result The original results reported that odd and even numbers are associated with masculinity and femininity, respectively. When pictures of babies were paired with odd or even “tracking” numbers, the babies paired with odd numbers were judged as more likely to be male, while the babies paired with even numbers were judged as more likely to be female.

Detailed Description of Method/Results Participants were told that they would see a sample of baby photos that were drawn from a larger bin of photos. The task was to rate the likelihood that each baby was male. Ratings of 1 indicated it was not at all likely the baby was male, while ratings of 7 indicated it was extremely likely the baby was male. Participants viewed 16 baby photos, one at a time, in a PowerPoint presentation displayed at the front of the room. The stimuli were obtained from the original authors. Half the photos were presented alongside an odd number (composed of three odd digits), and half the photos were presented alongside an even number (composed of three even digits). Participants were told that these numbers were tracking numbers, and that they could be ignored. The pairing of each photo with an odd or even number was counterbalanced across two versions of the procedure. As participants viewed each photo they provided their ratings on a piece of paper, and when the procedure was over participants wrote on the backs of their papers how they made their ratings. No participant indicated referring to the tracking numbers in any way while making their ratings.

A paired-samples t-test showed that the average rating of photos paired with an odd tracking number (M = 4.22, SD = 0.43) is not significantly different than the average rating of photos paired with an even tracking number (M = 4.21, SD = 0.53), t(36) = 0.15, SE = 0.12, p = .88.
Any Known Methodological Differences
(between original and present study)?
The original study recruited participants from MTurk, and their procedure was presumably computer-based. Participants in the current replication attempt completed the activity in small groups of 4-10, and they viewed the stimuli on a projector at the front of the classroom while providing responses on a piece of paper.
