| K52 (candidate) | Randomised trial in a university genetics course (N = 754): among students with high self-reported prior knowledge, off-topic interest clips raised perceived learning (7.05 vs 7.67, p = 0.011) with no quiz or exam difference; one of many uncorrected subgroup tests.

- Design: two large undergraduate genetics course sections (N = 754) randomised between subjects: 389 control, 365 with seductive details. Control videos totalled 7 h 41 min over the intervention; the seductive-details group got the same lecture videos plus two off-topic clips of about 1 minute each per class session for the first 4 weeks (17 min 13 s in total; 7 h 58 min of video). Clips were visually marked "Genetics Applied Around Us" segments, narrated by a different instructor; students were told they were only for interest and would not be tested.
- Outcomes: pre-class video quizzes (4 questions, 2 points; 92 % "apply"-level problems; online, retakes allowed), midterm 1, final exam, course percentage; interest, perceived relevance, perceived learning.
- Results: quiz mean 1.67 (SD 0.27) control vs 1.68 (SD 0.28); midterm 74.66 vs 75.76 (p = .389); final exam 164.38 vs 165.22 (p = .716); final course percentage 84.75 vs 85.05 (p = .730). No difference in interest or perceived relevance; students with high self-reported prior knowledge reported more perceived learning with the clips (7.67 vs 7.05, p = .011) without a score difference.
Role for C8
Limits (weaken, 2026-10-08): the largest randomised test in an authentic course found no harm from interesting but irrelevant extras on apply-level quizzes or exams. Not a kill: the clips were flagged as not for the test (Tislar & Steelman 2021 report a lab study, Eitel et al. 2019, in which the harm appeared only when learners were not told the details were irrelevant), added about 4 % more video time, quizzes were online with retakes, and meta-analytic averages from controlled experiments remain negative.
