| C8 | Confound-controlled lab study (extras matched for length and reading level): no main effect of seductive details on transfer; a harm only in a follow-up comparison when learning objectives were given, after a non-significant overall test (p = .07). C8 weakened 2026-10-08 (consistency bound); description corrected 2026-10-23. |
| K50 (candidate) | Lab study with extras matched for length and reading level: no main effect of detail type on core-content scores (F(2,103) = 1.19, p = .31); a harm only when learning objectives were given. Full text read. |

- Design: 3 × 2 between subjects; 132 undergraduates, 22 excluded for geology background, 110 analysed. Lesson with eight content screens (987 words of core content) with no extra details, low-interest details (+458 words) or high-interest seductive details (+464 words); low- and high-interest details matched for length (57 vs 58 words) and reading level (10.19 vs 10.16), pre-rated for interest and importance. Study time not limited; tests immediately after (core content, details, transfer; 10 min each for core and transfer).
- Transfer (0–5): no main effect of detail type, F(2,103) = 2.11, p = .13; detail × objectives interaction p = .04. With objectives: overall test of detail type not significant (F(2,52) = 2.80, p = .07); follow-up comparisons no details 4.11 vs high-interest 3.36 (p = .04, d = 0.72), low-interest 4.08 vs high-interest 3.36 (p = .07). Without objectives: no difference between no details and high-interest (p = .21); low-interest details scored higher than no details (4.39 vs 3.7, p = .04, d = 0.71).
- Context reported by the authors: Rey 2012 counted 11 of 39 experiments supporting the effect, 13 mixed, 15 not; a 2019 Applied Cognitive Psychology special issue had 11 related papers, five supporting the effect; in Eitel et al. 2019 seductive details hurt performance only when learners were not told they were irrelevant.
Role for C8
Limits (weaken, 2026-10-08, together with Maloy et al. 2019): with confounds removed, the harm to transfer was not consistent. Not a kill: a harm did appear when learning objectives were given, and meta-analytic averages remain negative.
Corrected 2026-10-23 (nightly attack run): the objectives-condition harm is a follow-up comparison after a non-significant overall test (p = .07), and some printed statistics do not add up (the same F(2,50) = 2.80 for the no-objectives test; core-content interaction printed with 1 numerator df; table cell sizes 110 vs 112).
