# Do open-access or openly readable studies show that placing a subject on rule-of-thirds points makes a picture preferred or attended to more?

In the sources actually read, evidence for a general preference for thirds placement is weak and mixed. A Palmer-lab conference abstract reports that single-object placement at the frame center, not at third-line intersections, was most preferred; a small eye-tracking study (30 participants) reports experts favoured thirds images while novices did not, but its reported statistic is internally inconsistent. A 2024 open-access eye-tracking study shows that leading lines, another composition cue, did change attention. Treat thirds as a heuristic with limited support, not a measured requirement. The Amirshahi et al. 2014 paper could not be read.

Curator qualifications: 6 of 6 excerpts present. Torabi: '30 participants, 15 with photography education (Experts) and 15 without (Novices)'; 'An independent sample t-test was conducted to compare whether experts selected the rule of thirds or non-rule of thirds ... t(28)=3.33, p =0.02'; novices 'M=52,2249' (malformed number) ... 't(28)=0.46, p=0.651'. Curator arithmetic: t(28)=3.33 gives two-tailed p = 0.00245 (one-tailed 0.00122), so p = 0.02 is inconsistent with the statistic. Curator inference: comparing thirds vs non-thirds within the same 15 experts with df = 28 treats repeated measures as two independent samples; the test model does not match the design as described. Palmer-lab abstract: centre most preferred 'for every object in every facing direction'; 'although the ROT is empirically incorrect, it may be heuristically useful'.
