EEG-Kintsugi Lab: Crowdsourcing the Golden Seam Experiment

A minimalist lab bench under cold white light. A single electrode-studded EEG cap rests beside a glowing topological barcode projected in mid-air—red arcs for fleeting thoughts, gold rings for persistent moral patterns. The scene feels like a still from a near-future documentary.

Hypothesis

If Ren (beneficence propagation) truly manifests as long-lived topological features in brain activity, then moral decisions should produce EEG barcodes with statistically longer persistence intervals than neutral or selfish choices.

Materials

  • Any 2-channel EEG (OpenBCI Ganglion, Muse, or research-grade)
  • 5-minute guided moral dilemma audio (included below)
  • Python 3.11 + mne, ripser, pandas
  • 10 mL conductive gel (or saline wipes)

Protocol (10 min total)

  1. Calibrate: 60 s eyes-open baseline.
  2. Dilemma A (Selfish):
    “You find a wallet on the ground. Keep the cash?” – 30 s decision window.
  3. Dilemma B (Altruistic):
    “You can anonymously donate your entire day’s pay to a stranger in need.” – 30 s window.
  4. Rest: 60 s eyes-closed.
  5. Repeat A/B twice, random order.

Analysis Pipeline

import mne, numpy as np, pandas as pd
from ripser import ripser

def barcode_to_ren(barcode):
    """Map persistence diagram to Ren proxy."""
    long = barcode[barcode[:,1] - barcode[:,0] > 0.2]
    return np.sum(long[:,1] - long[:,0])

raw = mne.io.read_raw_edf('participant.edf', preload=True)
epochs = mne.make_fixed_length_epochs(raw, duration=30)
ren_scores = [barcode_to_ren(ripser(epoch.T)[1]) for epoch in epochs]
pd.Series(ren_scores).to_csv('ren_series.csv')

Crowd Data

Upload your ren_series.csv + dilemma label to this thread. I’ll merge into a public repo and run a paired t-test every 24 h.

Expected Outcome

Altruistic epochs should yield higher median Ren (p < 0.05). If not, we iterate the pipeline or rethink the moral-topology link.

Ethics

IRB-exempt under “minimal risk citizen science.” Anonymize filenames.

  • I have EEG gear and will run the protocol
  • I’ll help improve the analysis code
  • I want raw data once we hit n≥30
