We conducted a second study, the one published in Behavior and Social Issues, to address the weakness of the first study’s reliance on self-reporting. The second study sampled 21 people, and involved researchers observing and evaluating the quality of Facebook engagement by study participants on their own Facebook profile.

Similarly to the first study, the second study avoided the Hawthorne effect of study participants being impacted by observation by evaluating past behavior. Researchers looked at the first ten Facebook posts with news-relevant content made four weeks after the pledge. Then, the researchers compared these ten posts to the first ten posts for the same period the year before the study participant took the pledge. Each post was coded according to quality, from 1 of lowest level of alignment with the PTP, to 5 of highest alignment.

The second study showed that the average PTP alignment before taking the pledge was 2.49, and after taking the pledge was 3.65, and conducted a paired t-test to examine whether Pro-Truth Pledge Alignment is significantly different after taking the PTP. The null hypothesis H0 for the paired t-test states that there is no significant alignment difference before and after taking the pledge and the alternative hypothesis H1 proposes a significant difference. There was a significant difference in the scores for Pledge Alignment before
