It seems likely that'd result in even worse suggestions becoming the norm as people adopt the third-party that gives the quick dopamine rush. It's like suggesting tastier heroin to fix drug addiction.
While the thing that gives you quick dopamine might win in the very short term, you can still step back and recognize when it's not satisfying in the long term and you're not even enjoying it that much.
And people aren't stupid. Junk food exists, yet lots of people choose to eat more wholesome food as the majority of their diet.
The problem with instagram or youtube is that you can't separate the good from the bad.
It's like if every time you went to store Y to buy milk, you would be exposed to highly manipulative marketing trying to get you to buy junk food. You would probably want to go to a different store instead.
What I'm suggesting is the possibilities of different stores, with different philosophies and standards, so that people can choose where they go. Corner stores (where almost everything is junk food) exist, yet people still choose to go to real supermarkets.
But that's very much the norm at supermarkets?
That's also true for heroin. Plenty of people really want to break the addiction.
The slop exists because people are attracted to it.
They've already built all the tools they need around this at the moment, it's just they give them to advertisers rather than end-users.
Absolutely not. It's much easier to make a one-time switch than to be continuously resisting temptation. Changing the things in your environment is an important tool to break bad habits. The book "Atomic Habits" talks about this at length.
