Title Failure to replicate McCabe & Castel

Brief Statement of Original Result The presence of a brain image increased ratings of agreement with a news article’s conclusions, and the presence of criticism had no effect. The presence of a brain image did not affect ratings of the appropriateness of the title, but the presence of criticism decreased ratings of the title.
Type of Replication Attempted Highly Direct Replication
Result Type Failure to Replicate
Difference? Opposite Direction, .40
Number of Subjects 99

Detailed Description of Method/Results Participants read one of four versions of a short news article entitled “Brain Scans Can Detect Criminals.” The articles either included a brain image or did not, and either had a short statement of criticism of the article’s conclusions or did not. After participants read the article they used a four-point scale to rate how appropriate they found the title and how much they agreed with the article’s conclusions. The study used a 2(Brain Image: Present vs. Absent) x 2 (Criticism: Present vs. Absent) Between-subjects design. There were 25 participants in each of the conditions, except for the Brain Image Absent/Criticism Absent condition which had 24 participants.

A 2x2 Between-subjects ANOVA on the ratings of agreement with the article’s conclusion showed no main effect of Brain Image, F(1,95) = 0.71, MSE = 0.36, p = .40, and a main effect of Criticism, F(1,95) = 5.36, MSE = 0.36, p = .02, partial eta squared = .05, in which ratings of agreement with the conclusion were higher when criticism was absent. There was no interaction between the two factors, F(1,95) = 1.28, MSE = 0.36, p = .26. The same type of ANOVA on the ratings of appropriateness of the title showed a significant main effect of Brain Image, F(1,95) = 4.98, MSE = 0.46, p = .03, partial eta squared = .05, in which ratings of the appropriateness of the title were higher when the brain image was absent. There was no main effect of Criticism, F(1,95) = 0.04, MSE = 0.46, p = .85. The interaction between the two factors was not significant, F(1,95) = 1.05, MSE = 0.46, p = .31.

Below are the averages and standard deviations of the ratings across conditions:

Ratings of agreement with the conclusions
Brain present, Criticism present: 2.58 (0.64)
Brain present, Criticism absent: 2.72 (0.68)
Brain absent, Criticism present: 2.54 (0.51)
Brain absent, Criticism absent: 2.96 (0.55)

Ratings of the appropriateness of the title
Brain present, Criticism present: 1.85 (0.67)
Brain present, Criticism absent: 1.96 (0.54)
Brain absent, Criticism present: 2.29 (0.69)
Brain absent, Criticism absent: 2.13 (0.80)
