A standard medical path, not a prodigy track

Born on January 19, 1976, in Ioannina to two teachers of Greek, Katsioulis studied medicine at the Aristotle University of Thessaloniki and specialised in psychiatry there. His record was strong but followed the ordinary Greek medical timeline.

Before settling into private practice in Thessaloniki he worked as a rural GP, a radiation-oncology house officer and an army doctor, and trained in forensic psychiatry. The full degree record is below.

That established career in an adjacent field is rare on the high-IQ-society circuit, and it shapes how he talks about his own scores.

Why breadth matters more than one high score

The Mega and Titan tests share a designer and a norming approach, so they tend to agree. Katsioulis's top results come from tests by different designers. Compare the two records.

Top results across three independent designers make it less likely the number reflects one test's quirks.

One umbrella, many thresholds

WIN verifies scores from many instruments and runs societies with entry points from the 99.9th to the 99.9999th percentile of test-takers. Drag to see what each rung means on a standard scale.

Critics note that accepting more tests also multiplies the caveats attached to each.

Under the WIN umbrella he founded a ladder of societies — QIQ, GRIQ, CIVIQ, HELLIQ, OLYMPIQ, the child society IQID and the GREEK IQ Society — and has been the public face of high-IQ societies in Greece for two decades.

Publications

Peer-reviewed research from his PhD and forensic-psychiatry training (listed below), plus essays on test methodology in WIN society journals — which aren't peer-reviewed in the same way.

Public profile

Kathimerini, Lifo and Greek TV have covered him with a steady focus on the dual career. He is measured in public, doesn't claim a single canonical IQ, and keeps his family life private.

Four degrees, five jobs, seven societies

All four degrees are from the Aristotle University of Thessaloniki. The left column is the education record; the right, what he has made.

“A single test score, even a very high one, is not a meaningful description of a person. The interesting question is consistency across many independent instruments.”

Reading the 198

High-ceiling tests are calibrated on small, self-selected samples. Read the figure as a ranking among people who take them, not as a WAIS-IV equivalent — a caveat Katsioulis applies to himself.
