p-values that are not in the physics ranges are ridiculous.

It's a shame everyone started copying physics but decided for higher acceptance/rejection values.

I was a little bit disappointed when I realized that a bunch of valid modern science is just proper experiment design and number crunching. If it's not physics, there's no models of why things work, there's just a p-value on the correlation or some other comparison function.

Medicine has turned into a field where you can't know a thing.

I love reading reports like the above:

> There is currently no evidence that supports or refutes that these interventions(chiropractic intervention) provide a clinically meaningful difference for pain or disability in people with [lower back pain] when compared to other interventions.

p-values really do not help that much.

P-values were developed outside of physics, it's not like people took them from physics relaxing the significance thresholds.
