Cracicot - you're on a witch hunt! So far you have shot down everyone who disagrees with you because they can't 'prove' you are wrong (and no one ever said that results definitely are not pre-determined, just that they don't believe they are for xyz reason). Well so far you haven't proved you are right. So how about instead of just talking non-stop about your theories, you actually do some rigorous testing according to the conditions you laid out and post the results? Ideally with some screenshots as evidence
As I'm sure you know, an accurate test requires both a large sample and the changing of only one variable at a time
