The geomagnetic field influences the empirical probability of probabilistic abstract decision-making. (A–C) Black stone (%) under different experimental conditions are indicated above each of the graphs. Note the significant differences in the black stone (%) in men (B) and women (C). (D,E) Blood glucose levels in different fast conditions were determined shortly before the first game of a stone selection experiment. GMF, geomagnetic field; Con, control (the ambient GMF); ≈ 0, near-zero GMF; Statistical values, mean ± standard error of the mean (SEM); N.S., not significant and ^#, p < 0.025, by the percentile bootstrap analysis; **, p < 0.01 by a two-sample t-test; horizontal dashed lines, the theoretical probability (50%) for black stone (%). The number of subjects in each group is indicated above bars in graphs.
