Objective truth isn't something you can know, but it's a destination that must exist for pursuit of knowledge/curiosity to have any meaning.

With contradictions you know what is not true, and through knowing what is not true, you can approach what is true. Truth is expressed in consistency, not completeness.

That's why anyone should be extremely suspicious of anyone who is not, or doesn't care about, being internally consistent.

You're getting downvoted because you're retreating into philosophical nihilism rather than actually addressing the points. If you disagree with how people interpret the studies, the studies themselves, or how science measures reality - just say that.

I also love SMBC's explanation of this: https://smbc-wiki.com/index.php/2010-09-23
