On the internet is there more information or disinformation?
I'd respond that this question is irrelevant to the thread at large for a few reasons:
1) Correct information has survival value
This means a few things. For one, people have an incentive to identify correct information amongst their available data set. This doesn't always mean they'll find it, but it means that they're at least looking for it, so given enough time the probability of them parsing through available misinformation is high.
It also means that people who are able to identify correct information and use it to survive are more likely to not only be alive to transmit that information to others, but they're also more likely to produce children and pass that information down their lineage.
2) Transmitting correct information has survival value
Ever seen the internet? It's a constant show of people trying to one up others by being 'right'. If I'm right and you're wrong, I'm smart, I get the girl or boy. In effect people are constantly trying to transmit correct information, unless they have some type of incentive to transmit incorrect data.
So not only are those who do this more likely to reproduce and pass on their knowledge, but the sum effect is that most human beings are 'correction robots' who are constantly trying to fix other people's knowledge.
Because of this, in the long run people will tend to become more informed rather than misinformed.
3) Incorrect information eventually dies
That's not to say it's never transmitted, or there aren't groups who exist as an echo chamber of misinformation, but the idea is that eventually ideas that don't work are abandoned, because even the holder gains nothing by holding on to it if they know it doesn't work.
So the sum effect of all of this is that truth and facts usually prevail in the long run, even if there's a bit of transient misinformation.
