"When you outsource the thinking, you outsource the learning." is so on-point.
"LLMs do not improve one’s writing ability much like taking a taxi does not improve one’s driving ability. ... What holds for writing is, of course, true for any cognitive skill to-be-learned in education, such as programming skills ... and these too suffer deskilling if not continuously practised"

Happy to share a new preprint in which @paulbuerkner.com and I introduce a novel model-based approach for precisely estimating the onset and offset of M/EEG effects!

Precise temporal localisation of M/EEG effects with Bayesian generalised additive multilevel models
Time-resolved electrophysiological measurements such as those obtained through magneto- and electroencephalography (M/EEG) offer a unique window onto the neural activity underlying cognitive processes...

Two quick points.
One, I wish we publicized and kept track of just how advocating for open science and especially replications impacts one's career. My personal experience & observation of students and ECRs working with me: it's very difficult. Challenges in every step.

Our new preprint explores what people with different visual imagery abilities 'see' during Ganzflicker-induced hallucinations. We used NLP + ML techniques to analyze descriptions from 4,000+ participants.

(And like, why are we still measuring researchers' productivity using number of outputs? I do not publish much but because I want to be reliable, replicable, and thoughtful. That's necessarily going to be slower but my work ends up in a "better" journal and being cited a little more.)

So if you can find that you can discriminate blue-seers from red-seers based on a determinable ground truth (e.g. brain response to red & blue stimuli), then this is meaningful. But what you -cannot- do is using people's brain patterns as an "objective" alternative to their self-report.

Can aphantasia be identified with a single question?:
"Visualise a place that you know very well in every possible detail (e.g., your workplace, your bedroom or your favourite bar). How vivid is the picture that comes before your mind's eye?"
