I noticed this phenomenon several years ago and came to the following conclusions: Romania is strongly multi-ethnic. Germans from Saxony and Swabia immigrated to Transylvania 800 years ago. A thousand years ago, people from northern India immigrated, whom we now know as Gypsies and who make up 8-10% of the population. In the south, the country was besieged by the Ottomans/Turks for 400 years. The cognitive differences between these ethnic groups are enormous.
Some time ago, I asked ChatGPT to find the winners of the Math Olympiads, their schools, and their places of birth. Most of the Olympiad winners attended elite schools in Bucharest, with few math participants coming from the south of the country and no participants who could be classified as Gypsies. But surprisingly many participants come from Transylvania.
In 2023, for example, a computer science Olympiad participant from Orăștie (Hunedoara County) won a silver medal. Orăștie is located in Transylvania and historically had a Saxon community. Brașov (Kronstadt) also recently produced medal winners: in 2025, a student from the Meșotă College in Brașov won silver at the Chemistry Olympiad. Cluj-Napoca (Klausenburg) also appears on the list – a student from the Bălcescu Lyceum there won silver at the Linguistics Olympiad in 2024. Timișoara (Temeswar)—also a western city with German history—was represented by a student (Carmen Sylva College) with an Honorable Mention in linguistics. These examples support the thesis that educational centers in the former Habsburg regions produce above-average talent.
Is there any further information about the ethnic origin of the Science Olympiad participants? I would be grateful for any information (even if it does not confirm the thesis).
