www.internetmatters.org misusing stats like this you have to wonder if there is a hidden agenda.
This stat could mean that 100% of 18 and 19 year olds have seen on-line porn and zero below 18 have seen any. It could mean anything. It depends on the age distribution of the sample, and all sorts. What is worse it is seen porn online, that could be anything from having seen page 3 of the sun on line over the shoulder of an adult at a PC, or some unwanted popup advert because they have not set sensible browser settings. It could mean anything.
As a stat it is completely meaningless. The age of people does matter - if there are 9 year olds actively watching online porn (or any porn) I would be very concerned. If we are talking of a 15 year old boy I would be totally unsurprised. If we are talking an 18 or 19 year old ADULT watching online porn then what is the problem at all?
Quoting that stat at the start of the video ruins any and all credibility of the rest of the video. What are they thinking?
Update: I was thinking more on this awful stat, and a couple more points come up, purely intuitively. 1. The taboo nature of the subject mean that even adults will deny seeing porn even when they have, but it is very unlikely someone would say they have when they have not. 2. The combination of both being taboo, and seen as wrong doing for a minor would mean children are far more likely to deny seeing porn than admit it. This means that the 57% who admit seeing online porn is probably a gross underestimate. 3. Even so, if 57% have done this terrible thing and society is not falling apart, that is a serious indicator that there is no actual problem to solve here. If the stat was 99% or 100% would we really not have to say "clearly this is perfectly normal and nothing to worry about"?
Thanks Alex for pointing it out to me.
