The problem is that the human brain is _extremely_ well-suited to taking
data and finding patterns in them, whether the patterns are there or
not. (I assume that this is because a false positive on "is there a
sabre-tooth hiding in that bush" is less of a problem than a false
When one thinks one observes a pattern it is vitally important to step
back from it and say "OK, I've observed this, but can it be backed up
by any objective method?".
So really it depends on what you mean by "making patterns" - people who
reckon they have found patterns in data that really are purely random
don't think they're making them up.
