How many world-class institutions does Iran hold?

Average quality and elite capacity disagree by construction, and both are worth knowing: the first is decided by a country's whole institution population, the second counts the institutions it holds at the top. One square per institution.

Standing among countries2022-nowWhere that sitsAll time
Average qualityits whole institution population #45 of 189 #43 of 203
Elite capacitythe institutions it holds at the top #45 of 204 #49 of 216

Elite capacity counts a country's institutions by their worldwide rank, weighted so a place at #1 counts for more than one at #480. Countries under 100 fractional works are left out.

501st to 1,000th1

Bands are exclusive, so the squares add up to 1 (the institutions it holds in the world top 1,000), not to four times it.

Similarity is the correlation of each side's location quotients across every field it publishes in, on a log scale: 1 is the same shape of research, 0 is unrelated. It ignores size. How it is measured.
