In the context of the water jars experiment, &quot;attitude&quot; is not the explanation though; instead it refers more to the &quot;installation&quot; of the previous solution in the subjects&#x27; minds (i.e. the subjects who were &quot;trained&quot; with the 5 pre-test examples effectively had those solutions installed&#x2F;set in their minds).<p>You see this in game development a lot- users are trained in the first 1-2 levels &quot;Here&#x27;s a puzzle - look around for clues&quot;. When they later encounter a puzzle in levels 3-n, they often apply the same methodology despite the obviousness that another approach is called for.<p>You see it in chess development - an app teaches users, &quot;Given a board with these positions, the best option is x&quot;. Later during growth, the same board positions may have different solutions yet the student continually applies the original.<p>Attitude isn&#x27;t at play here; it&#x27;s simply <i>expectation</i>.
