"Measured: 0.5257 proportion of heads whose larger parastichy family runs clockwise (photoreviewed counts) (n = 272, exact 95% CI 0.465-0.586; two-sided binomial P = 0.43). Interpretation: Thompson's 'direction' of the five-series (right- versus left-handed spiral) is mapped to the chirality of the larger parastichy family of a Fibonacci-type pair, scored as clockwise or anticlockwise in a fixed viewing convention (the seed face of the head as photographed). Thompson's own counts are of Norway spruce cones; no public per-cone table of those counts exists, so the test is a replication in another phyllotactic system (sunflower capitula), which the claim explicitly extends to ('phyllotactic systems generally'). Thompson's own 224:243 split is reported alongside for comparison but is not used as data." . "Claim test of thompson1917-ch14-06: supports, confidence 0.85" . . .

"Heads whose two counts did not form an adjacent Fibonacci-type pair (about 40% of photoreviewed heads with two counts) were excluded by the pre-registered rule; chirality in disordered heads is not tested." . "The 21/34 class (n = 29) leans right-handed (20:9, P = 0.06); it passes the pre-registered class rule only through its P value, and the two large classes lean in opposite directions, consistent with chance." .

Define a head as right-handed when its larger family is clockwise. Pooled over all such heads, the proportion p of right-handed heads must satisfy |p - 0.5| <= 0.10 and a two-sided exact binomial test against 0.5 must give P >= 0.05.
