Maybe you’re not trying

> Also, people are made up of particles that behave deterministically. Agency is an illusion.

I like to slap people talking this to my face. Why? I was predetermined to slap them, the universe was set up that way. But I had only one occasion to really do this. The guy was thinking about this for two days. And when I say about this every proponent of "Agency is an illusion" then has some cop-out about responsibility, because in truth they use "no agency" as an excuse to explain their bad behavior.

Most people will accept a brain tumor as an excuse for bad behavior, but not low blood sugar.

I have successfully convinced people that hungry judges have less agency than full ones, though. (google hungry judge effect if you're curious).

As a person who would like to excuse my overeating on confirmed problems with blood sugar, I agree with you fully. We have different amount of willpower in different situations and in the same situation between different times of day. But we still have some agency, it's not fully predetermined. And like being overweight, training can help. I would even say that combating fat needs willpower and increases your available willpower too.

That's not my position at all. Obviously you had no agency in your genetics. I assume you don't believe you had agency in pre-natal nutrition or the circumstance of your upbringing.

The rest of your life is just reacting to things downstream from that with an algorithm based on your nature and your nurture.

If it weren't for quantum effects you could model the outcome and it would be the same every time.

> That's not my position at all.

I would like to understand your position more. Most people believe that they have choice. They could for example do more work or lie on a couch. You mean they have no choice and whichever decision they took is not from their will, but only from their circumstances? I agree that a lot of the weights in such decision is a result of previous happenstances, but "no agency" model suggests to me that we can't make any serious changes in our life, because whatever happens, happens and maybe we were not destined to change our life. This further suggests: "why even try".

I believe OP's original implied position was "the universe is deterministic, so why even try", but I was able to convince them that trying is worth it regardless. In fact, the universe being deterministic would mean that it's always worth it to believe that you can accomplish something (if you want to increase the probability of accomplishing that thing).

> You mean they have no choice and whichever decision they took is not from their will, but only from their circumstances?

It is from their will, but a person's will is either completely or partially derived from circumstances. If you believe that the universe is deterministic, then a person's will (brain and body state) is completely derived from their circumstances (prior interactions with the rest of the world).
