"'Often mistaken, never in doubt." That wry phrase describes us all more than we'd like to admit.'
The psychological study of misconceptions shows that all of us possess many beliefs that are flawed or flat-out wrong—and also that we cling to these fallacies with remarkable tenacity. Although much of this research concerns misguided notions of how the physical world works, the techniques it has produced can be used to correct any sort of deficient understanding."
