Ugh, so many responses miss the points about personal bias and qualifications: (and yes, the OP must have known they would get flamed)
Not everyone is educated and unbiased enough to make good (good = net positive impact on the game in a way that can be measured) game design choices. Those same people are more likely to not realize that their choices aren't universal truths.
Newsflash, and I won't be shocked if this is controversial: Not every personal conclusion is equal to the rest. Some opinions are much more informed than others. Some opinions are more narrow minded than others. Some opinions are more influenced by personal preference and bias than others.
The world has come to a place where personal feelings and opinions are respected, but this attitude has bled over into science vs fiction. But facts and science still exist. Knowledge and reason should count more than feelings when it comes to real things, like game design. (Knowledge ABOUT Feelings is still important, as the product is a game and games work with feelings).
Unfortunately this is an internet forum and everyone gets to think their ideas are better than the rest and there is no vetting or review process to filter things out. Thus, you are just as likely to encounter a screwball idea as you are to see a well thought out and reasoned idea.
I once had an argument with a guy about plastic nanoparticles passing through skin cell walls and causing problems. I have a lot of scientific background, enough to understand molecules and the difference between eating with a plastic spoon and burning a plastic spoon while inhaling the vapors before they have time to decay. The other guy had a "feeling" that nanoparticles are fine because plastic is everywhere in our lives and we eat with plastic.
He DEMANDED that his POV be taken with full respect, and that he be allowed to advise other people about his opinion while stating it as a matter of fact.
