Not sure why you mentioned chiropractors, I thought this was about scientific things.

The Big Bang Theory, ... and this despite the fact that I believe the universe is expanding now. This expansion is still accelerating so the small acceleration itself could result in the expansion (speed distribution) without having to postulate an extremely rapid acceleration at time zero and other ludicrous extreme physical conditions.
... and yes I know also about the cosmological microwave background's perfect black body curve and such observations.
It’s got to be Dark Matter. So many astrophysicists have spent so much time thinking about this stuff and all they’re really sure about is that there must be much more matter in the Universe than we can see, and yet we never actually seem any closer to knowing what it is. In conjunction with Dark Energy it just leaves the layman with the awkward possibility that maybe our model of The Universe is just fundamentally flawed somehow.
Lots of stuff from both social sciences and economics.
Social science suffers greatly from the Replication crisis
Economics relies largely on so-called natural experiments that have poor variable controls.
Both often come with policy agendas pushing for results.
I take their conclusions with a grain of salt.
we should totally revoke the degrees of chiropractors. And the ones of psychoanalysts while we are at it.
