Participants had to solve arithmetic problems, presented as water-jug problems, where one has to fill one jug with the right amount of water by using jugs of different capacities. The first five problems could be solved with the same solution. Problems 6 and 7, called critical problems, could be solved both by the same solution and a shorter solution. Eighty per cent of the participants used the familiar solution and failed to see the shorter one. Finally, problem 8, called the extinction problem, could be solved only with the short solution. Surprisingly, nearly two thirds of the participants could not solve the problem. This level of failure cannot be explained by the difficulty of the extinction problem, because it was solved by ninety-five per cent of the participants in a control group that did not receive the first five problems. Luchins’ study illustrates how entrenchment and the automatisation of thought might lead to unsuccessful problem solving.” (Gobet, 2017, p. 5) ##### why does it matter? >“experts, who have acquired considerable knowledge and automatised their skills, have a more rigid mode of thinking and are actually more prone to the Einstellung effect than novices.” (Gobet, 2017, p. 5) ##### This reminds me of ##### What would the opposite argument be? tags: #note/growing ##### Sources: Gobet, F.
