I've observed that many people react badly when presented with instructions that come with a purchased product. ("I can't/don't read manuals," etc.) This bias tends to sabotage their attempts to follow them once they do concede that the instructions might be useful. ("See? These instructions are useless, that's why I never bother with them.") Combine this with the fact that spatial-temporal reasoning skill seems to vary quite a bit across the population.

If you've ever watched Canada's Worst Handyman, you'll see that this kind of attitude is quite prevalent with them. Now I know that this doesn't give us causation, but it's a pretty strong correlation.

After watching a few videos from that show, I swear we have hired some of those people to do work on our rental properties. I have some pictures of bad work that I really need to put up on my blog.
