WHY PSYCHOTHERAPY LACKS SCIENTIFIC EVIDENCE

THOUGHTS AND EMOTION ARE CAUSAL EPIPHENOMENONS WITHOUT CONSEQUENCES

- thoughts/cognitions, feelings/emotions and actions/behavior are consequences of an underlying anatomical, biochemical or electrophysiological state or process
- thoughts and emotions are not physical entities and therefore they are causal epiphenomenons: they can/do not have any consequences of their own
- the phenomenons supposedly caused by thoughts and emotions are rather consequences of physical states/processes. these phenomenons and their respective corresponding thoughts/emotions occur jointly because they share a common cause/confounder
- neural correlates of action predate both thoughts and emotions (Libet experiment)
- emotions (phylogenetically ancient brain regions) predate thoughts (neocortical regions): defeatist thoughts therefore cannot possibly cause sadness


FALSE CLAIMS OF A COGNITVE BASIS FOR MOTIVATION

- cognitivism gives short, catchy and superfically sound explanations, but does not align with reality
- motivation (from latin "movere" = to move) has nothing to do with cognition: one can be highly motivated to do certain things, yet indifferent or even unwilling
- counterexample: akathisia (extrapyramidal hyperkinesia caused by DRD2 antagonists or Parkinson), usually perceived as distressing, but immense motivation
- counterexample: obsessive-compulsive disorder, highly motivated, yet unwilling
- counterexample: the addition of extrinsic motivators to intrinsic motivator decreases, rather than increases overall motivation. if cognitivism was true, the effects should be additive.

What keeps you motivated?
How could I possibly improve my self discipline?

Any advice?

What is love?

i just cant solve multistep physics problems. i dont know what it is. i have no intuition for it. im bad at lengthy math proofs as well.

f(x) = x^4 - 2x^2 + 2
1. prove f(x) is irreducible over Q (easy)
2. find the zeroes of f(x)
3. If E is the splitting field of f(x) over Q, prove that [E:F] > 4
4. prove that Gal(E/F) is isomorphic to D4

The last two parts would have been easy if I just had the right roots, instead I had to bullshit my way through it with answers I knew were wrong, but hopefully I'll get some points for being somewhere in the ballpark in terms of method.

I fucked up a fairly easy exam, because I forgot that a certain family of functions has a tricky representation that can be simplified by a simple substitution.

I knew all the theory, but nothing quite worked because I got an overly complicated function to work with that made everything impossible.

And I knew about the substitution as well. It just wasn't something I thought was important because it is just tangential to the material in the class.

How do you keep yourselves sane when shit like this happens? It just seems so much a matter of luck that you can get a C instead of an A because of some bullshit reason like this.
