This view presupposes that things "we can perform without thinking about them" are done correctly. We don't get there without thinking about them first. Doing things without thinking about them is, at the level of each individual, a luxury we earn by thinking about them really hard at first. At the scale of society, well, this is supposedly what school is for. But for the society to "not think about" things, individuals have to continue thinking about them.

A lot of people don't get that far for a lot of tasks, so "think more" is not incorrect advice for them.
