You have a finite attention span because you are human. also limited comprehension and time for same reason. So, you will always end up in a bubble of one kind or the other. Even if you only decide something as natural as to dedicate yourself deeply to some skill pursuit or craft, you will consume that info to the detriment of all other info for some period of time. So the focus cannot be some meta construct that filters info up front. Instead you have to just develop some good research and discernment skills. Brush up on argumentation and some symbolic logic and maybe some on examination of evidence. Its the thinking tools that will allow you to consume willy nilly and curiously without worrying that you will be bamboozled.
That is the hard way. Easier way is just pick an "us" group and ride or die with them. That way at least your bubble supports your personal community of frens and such.
