Scientists believe studies by colleagues are more prone to biases than their own studies
The properties of human mind affect the quality of scientific knowledge through the insertion of unconscious cognitive biases. Scientists from the University of Turku, Finland, have found that the current level of awareness about research biases is generally low among ecology scientists. Underestimation of the risks associated with unconscious cognitive biases prevents avoiding these risks in a scientist's own research. Due to unconscious origin of biases, it is impossible to combat them without external intervention. (2021-02-03)
