I just saw a prestigious postdoc scheme that needs *three* letters of recommendation just to apply Imv this is deeply unethical. This is why PhDs don't speak out about bad practice and malfeasance from their advisors three letters = speaking out loses your career chances

You'd think people prefer the simplest explanation of an uncertain world — Occam's razor. Our data says no, across 2 modalities, 2 tasks, 8 experiments: people often perceive illusory structure that isn't there and prefer moderate complexity. Out now in Nature Comms! www.nature.com/articles/s41...

When children learn addition, they follow a weird learning trajectory that is held to reflect their metacognitive rewriting system. In a new CogSci paper with Frank Mollica and @perfors.net, we show that the trajectory is explained by environmental pressures: imitation, followed by speed or accuracy
Plot from the paper of model simulations reconstructing the aforementioned trajectory: sum to shortcut to count from to min.

If these effects accumulate over months and years of daily AI use, by the time they're visible they may be very hard to reverse aka the "boiling frog" dynamic. Each individual act of using AI feels costless but the cumulative effect may not be.

is a balloon more conscious than a piece of rock? i think it is. consciousness refers to the capacity to respond meaningfully & interestingly to external stimuli. a rock doesn't do much when we kick it. the balloon, however... is so 'fun' so play with. so unpredictable. it has a real personality

Humans have a remarkable capacity for efficient, intelligent reasoning. In a new working paper, @perfors.net and I discuss how our ability to reason from *social* information is one way that we achieve this capacity. osf.io/preprints/ps...
Figure from the paper. How does social reasoning enable efficient intelligence? 1. Directs us to the information that is most important for learning. 2. Inferences about others' minds help us interpret information they provide (and provide better information for others). 3. Avoids some of the costs of direct learning like cognitive/physical effort, and negative outcomes. 4. Enables us to build on and refine the knowledge of others. 5. Provides cues that help us infer which agents' knowledge we should build on without needing to observe their behaviour directly.

What they want is some path out of that, and someone who is proud and unashamed of being sincere -- who in fact points out that rejection of meaning and failure to stand for anything is the coward's way out -- provides that path. We can't be apologetic. Standing proudly is its own proof of concept.

Thinking about this quote from Persepolis creator Marjane Satrapi again.
Picture of Marjane Satrapi alongside a quote from her. The quote reads:

The world is not divided into countries. The world is not divided between East and West. You are American, I am Iranian, we don't know each other, but we talk together and we understand each other perfectly. The difference between you and your government is much bigger than the difference between you and me. And the difference between me and my government is much bigger than the difference between me and you.

And our governments are very much the same...

It's a struggle, but it's gratifying once things start coming together. What I have on paper tonight is a clean expression of idea I didn't have well-formed when I began this morning. Some people think we should hand off this painstaking form of labor to LLMs and get back to doing science.

When there is a random way to do something, there is a less random way that is better but requires more thought. In this case, regression models that make no sense don't belong in a multiverse analysis. An inferential regression without a causal justification is like an opinion without reasons.
