“Those with the strongest habits who were the least successful in predicting their behaviour over the coming week were the most confident in their predictions. The finding is striking because it hints at one of the dark sides of habits. When we perform an action repeatedly, its familiarity seems to bleed back into our judgments about that behavior. We end up feeling we have more control over precisely the behaviours that, in reality, we have the least control over. It’s another example of our thought processes working in the opposite way to our intuitive expectations.” – Dean 2013, 22
