This has me thinking, as I read it when you had first posted.
Yes, and no..is.
Yes, because results can be skewed with several variables.
Online interactions are afforded the ambiguity of anonymity, allowing for false presentations at times.
People aren't privy to that "real time", "right around the corner" face to face interactions, so as to actually see/feel/hear the emotes afforded , that are absent with "online" behind a computer screen.
Behind the cloak of a screen is an "emotionless" encounter...as you can't SEE reality. Say for instance, Road Rage, this isn't possible to see or hear online. Perhaps there is a third eye (in Chakras, YES there is) but this is literally....you wouldn't necessarily see that from behind the confines of a screen. Not a big deal for me, per se, but it may be for others.
No, because online is in "cyber world"..and in "cyber world" everyone is "awesome" and wonderful and has such riches and degrees and whatever persona they may wish to create. So it wouldn't lend credence to a positive wet bias, but as LWF said a "false positive wet bias".
This is my own opinion and isn't meant to be negative or derogatory or accusatory to anyone or any situation...am just joining the htread...voicing my personal thoughts
