Can Brain Scans Detect Pedophiles? | 80beats

Using fMRI, the researchers recorded their brains’ responses and found that by comparing an individual’s brain to the average of the pedophiles and the average of the controls, they could assign them to the correct group more than 90% of the time. Their handling of the statistics avoids the most obvious pitfalls: they used an analyses technique called leave-one-out cross-validation to avoid comparing a given scan to an average that includes it, a common error in neuro studies.
