I'll take a look at this link later and possibly look up that book too. I do want to say a few things however that so far it seems every replier seems to be mistaking as a larger whole.
These people seem to think that humans aren't at fault for the actions of their creations. They seem to think that algorithms are capable of having agency for their actions... This couldn't be further from the case.
As for the content of your reply however, thanks for being a little more nuanced in it all. Yes, a self contained echo chamber is definitely not going to help things. That said, what you are saying is effectively saying as well "If you proofread your own comments, you are risking radicalizing yourself off your own ideas." But further than that, you are also stating "Those ideas are just half baked".
Well in some people's cases that may be true, but as per the usual problem with most of these arguements; it leaps right past the true actionable agent in the problem and heads straight for blaming X thing that people have little control over. Psychology is one of those things that people have less control over than other people would like to believe. I know this because I have had to literally retrain psychologists over stuff like this during the times they figured they were fixing me. HAH, jokes on them.
(It was always something like "Those people don't control your actions" and I would always reply with "When did the chain of actions and consequences begin in your mind over this subject matter?". To this they would usually start it with 'me', when I would correct them and say "it starts with the person before I, because my actions are based off the consequences of their actions. Therefore while they may not 'Make me' do anything, they certainly do present possible options for me to take, and I tend to take the ones that they like the least; usually due to them being the correct action."
Now, from that little bit of a side story, do you see how your opinion of psychology being the answer might be a bit of problem in its own right? Your assumption basically ignores the fact that there is a chain of consequences for every action taken by every single person connected to said subject matter.
So while the person proofreading their comment might be 'radicalizing themselves' using their own propoganda; you are making the mistake of thinking that just because they have X opinion other than yours, it must be bad. This is a common mistake made by... drum roll please... radicalized people. Especially so in regards to folk who are on the internet far more than they should be? I end that with a question mark because it's mostly an observation so far that I cannot concretely say is for certain the problem and cause to the problem.
And so now we are back to the crux of your point. The half baked idea that gets reiterated over and over again due to be re-read. How half baked is my reply to you? How half baked is your reply to me? Was my original comment even half baked to begin with, or is that just your view of the situation through your own subjective and thus potentially biased viewpoint? Get the point?
The problem is many things DyslexicAtheist. But all of them stem from one single source. Humans. This is why I blame them and not the algorithms or the psychology itself. Why?
Because both are creations of humans. Psychology is just an attempt to understand something we didn't create, so we created a method of understanding it. Faulty as it may be, it has its uses. Algorithms are the same thing in a way. We created the fabric of which they exist, but we still don't understand fully how they operate. Or to put it a better way, we don't fully understand yet how to create them to make them operate exactly how we want. And then furthermore from there, we also do know how to create them well enough to make them do exactly what we want from time to time as well; which has its own problems.
Youtube's algorithm is a good example of the creators only having a partial understanding of how their creation works. (If they are to be believed every time they say "we aren't sure how this works")
Twitters is on the other hand a good example of them making an algorithm to do exactly what they want it to do, and it does it really well. To horrific results.
Both together are my point insofar that algorithms and psychology are only part of the general overall answer. They are not the end all or be all. Humanity is that, in regards to this problem. We are the one factor that if removed, all the problems cease to exist. But we can't exactly go removing ourselves... Well, we can... but that has new problems attached to it.
Meanwhile, the people with the half baked ideas as you put it, are just stating their opinions. You may call them half baked, but who are you to judge others opinions when yours probably aren't that great either to begin with? right?
And that right there is the real source of all the problems. People's ego's.
Once you get over your ego, all of this becomes much easier to understand and accept. But getting a human to do that is fucking hard.
