Human nature precludes one person from being objective in all cases.
FWIW, The most horrible thing I've ever heard was about an individual who spent an entire round, their first time around a specific venue, influencing others on the merits, of a specific design.
This same person is well known for planting seeds that get regurgitated throughout these annals, all the time.
The verdict is that most of us are way too easily influenced, if something as trifle as a comment, can sway someone else into believing it as gospel, to the point of brain washing.
