Opinion and analysis on EEG, equity, and hardware that works for everyone.
Medical devices are validated on narrow populations, then assumed to work for everyone, and the gap shows up as silence rather than data. Pulse oximeters, AI skin cancer classifiers and EEG all share the same failure. Inclusion is not a moral nicety, it is a precondition for the science being true, not kind.
Standard electrodes work through fine, straight hair and struggle through everything else. That is not a law of physics, it is a design decision that quietly excluded whole populations from neuroscience. Here is why it happened, and why it is fixable.
More pieces are on the way. If there is something you think we should write about, tell us.
