Large-scale assessment of the effect of popularity on the reliability of research.

Using a logistic regression on the model ln(w ij /(1−w ij )) = a+b ln(P i P j ) , we observe a highly significant negative correlation between confirmation probability w ij and log-transformed popularities of the interaction partners ( a = −1.41±0.04; b = −0.020±0.005, p = 4.8*10 −5 ; N = 62,864 statements).
