People who say levels are easy have often only done the level once or twice, because they get out early and then move on, and never play it again. But they don't understand the concept of probability. You can get lucky on a hard level and get out first time. That doesn't make it easy. It means you got lucky. You can only have a reliable opinion on the difficulty of a level if you have played it a large number of times. If you get out every time, it's easy. If you get out only rarely, it's hard. If  you've only tried once, you don't know whether it's easy or hard (whether you got out or not). If the vast majority of votes agree on difficulty, that can be a reliable indicator. But if there is disagreement, votes on difficulty should be  weighted by the number of times the voter has played. That will give a bias towards 'hard' (because people tend not to repeat levels they've completed), but it's better than accepting as equal the 'easy' votes of a few lucky people.
