Not having access to his research, I really don’t know on what basis Prof Hood draws his conclusions, but, if the linked-to report is accurate, it is likely that he has sound reasons for voicing them. His observations also accord with a study in the US that was done which I read about some time ago - unfortunately I don’t remember which book it was.
The study was on the effect education has on superstitious beliefs. A group of first-year university students (about 300, as I recall) were given an assessment test at the commencement of a six-month course in critical thinking, said test gauging their degree of superstitiousness. The same test was given shortly after the completion of the course, and again two years later.
As one might expect, the level of superstitiousness dropped markedly between the first test and the second one. Significantly, however, the third test showed no difference from the first, and these were university students who are above the average national intelligence, who one might expect would be more amenable to retaining the acquired thinking skills.
The lesson to be drawn from the above is, yes, education alleviates sloppy thinking temporarily, but absent (positive) reinforcement thereof, people will tend to revert to their original ways.
And I have no problem with the way that science proceeds. One must remember, though, that science is a communal enterprise, not an individual one, in the sense that an individual’s sloppy thinking will be discovered sooner or later. That in itself is much of a deterrent against carelessness, but not an ironclad guarantee. Sure, separate ideas originate with individuals, but they are hardly representative of the totality of humans.
Much of our day-to-day thinking is such that we can get away with cerebral sloppiness. It doesn’t matter much whether I believe that fire will quickly burn me because of the high thermal gradient between the flame and my hand, or because the fire god doesn’t like being touched by humans. In either case, the effect is the same in that I am careful around fire.
So while science, through its methods, aims to transcend such functional thinking by attempting to trace back to the real nature of things, individual humans are generally happy to accept as valid without further question those ideas which experience has taught them seem to work.
