But it may not take coercive suggestion to affect a person’s memories. The testimony of eyewitnesses is notoriously subject to suggestion and to error, frequently with dire effects on the wrongfully accused. 6 With the advent of DNA testing, it is now possible to find, in many cases, an objective corroboration or refutation of such testimony, and Schacter notes that “a recent analysis of forty cases in which DNA evidence established the innocence of wrongly imprisoned individuals revealed that thirty-six of them (90 percent) involved mistaken eyewitness identification.”
Cannabis enables nonmusicians to know a little about what it is like to be a musician, and nonartists to grasp the joys of art. But I am neither an artist nor a musician. What about my own scientific work? While I find a curious disinclination to think of my professional concerns when high – the attractive intellectual adventures always seem to be in every other area – I have made a conscious effort to think of a few particularly difficult current problems in my field when high. It works, at least to a degree. I find I can bring to bear, for example, a range of relevant experimental facts which appear to be mutually inconsistent. So far, so good. At least the recall works. Then in trying to conceive of a way of reconciling the disparate facts, I was able to come up with a very bizarre possibility, one that I’m sure I would never have thought of down. I’ve written a paper which mentions this idea in passing. I think it’s very unlikely to be true, but it has consequences which are experimentally testable, which is the hallmark of an acceptable theory.
