Weak supporting evidence can undermine belief in an outcome

Experiments by Brown University psychologists have produced positive evidence that people often think about positive evidence the wrong way — if it is weak. Defying logic, people given weak evidence can regard predictions supported by that evidence as less likely than if they aren’t given the evidence at all.

Can you predict your mate will cheat by their voice?

The study also detailed the most recurrent forms of abuse, as well as the variables associated to them.

Better brain wiring linked to family genes

The study published in the international publication The Journal of Neuroscience provides the first evidence of a genetic effect on how ‘cost-efficient’ our brain network wiring is, shedding light on some of the brain’s make up.
