I believe 100% it's unintentional for most people. Only the ones making money are doing it on purpose. Most PEOPLE in general don't have a linear thought process, their have an associative one. Stimulus response plus operant conditioning and that's the extent of most people's "reasoning"

Summed up, there are more stupid reasons to believe true things than good reasons. So just because somebody's conclusions are right doesn't make them not retarded.
