> Real life echo chambers reinforce that as well if you only interact with people with similar lifestyles and worldviews.

I'm not sure that's a truism. But we'll have to agree to disagree here.

Certainly the reverse (anti-echo chambers?) isn't true (which casts doubt on the original statement, for me): cf current US Republicans politicians who constantly interact with people that have different lifestyles and worldviews[0] without it having the slightest effect on their own worldview.

See also: anti-vaxxers, flat earthers, and, extreme[1] religious people; all of whom cannot fail to mix with people of opposing views nearly every day without it changing their minds.

[0] As a small example, they mingle, have lunch, holiday, serve on committees with, etc., their Democrat colleagues all the time and yet not a shred of sanity rubs off on them.

[1] The more culty end of the spectrum; you know the ones.
