Children’s capacity to draw quantitative Bayesian inferences appears to be limited.Children perform equally well with natural frequencies and number of chances.Children’s Bayesian inferences can be improved by fostering extensional reasoning.
Distinction between quantical (number discrimination) and number abilities (more symbolic abilities) makes it unlikely that human beings' numerical abilities have biological origin. Rather, the latter may well be cultural products.
