brains, and data.

Human and machine behavior

Background: 2410 s of nasal breathing, one participant, recorded at 1 kHz, shown at 25 Hz. Watching it may change yours: Somatic UX. data Ph.D. lab recording, raw, not public

Human

Hexadecanal, C16H32O. The body volatile that blocks aggression in men and triggers it in women. paper Sci. Adv. 2021 structure PubChem

Chemical signals

human chemical communication

What the sleep-quality model listens to. SHAP values for its 8 strongest features, 500 reports each. Darker is a higher feature value. 4,794 participants, 759,116 reports. paper under review data anonymized release, forthcoming

Body signals

subjective states from wearable physiology

Noise-blast level chosen in each of 27 rounds. Left to right: men control, men HEX, women control, women HEX. Darker is louder. n = 130. paper Sci. Adv. 2021, Fig. 2B data Mendeley, TAP_FullData.csv

Behavioral signals

human behavior meets product

Machine

Blind evals against 15 real startup post-mortems. One row per company, one mark per documented failure mode: caught (light to dark, easy to hard) or missed (dot). 61 of 78 caught. paper internal benchmark data 15 public post-mortems, private repo

Evals

how do you build ground truth for long, open-ended conversations?

AI in research how do researchers actually use AI, stage by stage?
Code-review ledger to automate review, we first need data: every AI finding and its disposition
Prompt pressure does emotional force with no new information change a model's verdict? Smoke runs on Haiku 4.5 and Sonnet 5.

Working on these now.
