Environment watchdog buried report on lead in children’s blood to placate mining companies, emails show

Documents tabled in NSW parliament show state agency took four years to publish report and told miners it would be put online ‘quietly’ but EPA says it was released to community earlier

Hi Zahra thanks for your interest ;), would you mind either sharing your email address here or send me a quick line @ [email protected]

Sepehr Razavi @srazavi.bsky.social · 27d

Feel free to reach out to me, or better yet, send an email to @joebarnby.com to receive a link to this talk. Looking forward to seeing many of you then :)

This work provides a mechanistic bridge between subjective beliefs about agency and their impact on learning and well-being.

Sepehr Razavi @srazavi.bsky.social · 27d

These studies also explore how agency-modulated reinforcement learning is represented in the brain, how it changes across development, how it is associated with early-life adversity, and how it is related to mental health symptoms.

Sepehr Razavi @srazavi.bsky.social · 27d

In this talk, Dr Dorfman will present a series of studies demonstrating that agency beliefs can modulate the extent to which individuals learn from positive relative to negative outcomes and that this process can be explained by a novel Bayesian reinforcement learning model.

Sepehr Razavi @srazavi.bsky.social · 27d

Agency beliefs have a substantial impact on mental health, but the mechanisms through which agency and mental health interact are unclear.

Sepehr Razavi @srazavi.bsky.social · 27d

However, it is often impossible to know for certain whether we have control over the environment, so we must instead make inferences and form beliefs about our agency.

Sepehr Razavi @srazavi.bsky.social · 27d

In order to navigate an uncertain world, we must make flexible predictions for maximizing rewards, minimizing punishments, and guiding future behavior. These predictions are most accurate, and feedback most useful, when our own actions are responsible for the consequences we receive.

"Assuming that functional specialisation necessarily implies an ‘encapsulated module’ is a widely recognised error even in evolutionary accounts."

What a brilliant group of people to work with! Looking forward to expanding some of the crucial ideas only touched upon here. Feel free to share your thoughts, insights, etc.

Academic publishing in the humanities really is all a crapshoot at the end of the day no matter how many improvements we try to find

Sepehr Razavi @srazavi.bsky.social · Aug 26

Your paper looks interesting and I am sorry you’re going through this. Unsolicited advice: to my non-expert eyes, what is missing is a sense of what hangs on this (even for Spinoza exegesis).

Congrats Chanelle :)
