INSUFFICIENT LEANING

Recorded sources

0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that all human cultures use base 10 for counting?

Unclear. Two reference items describe counting systems that lack a base-10 structure, including a body-part system with no base and Maya numerals lacking a decimal separator. Neither item surveys all human cultures, so they only partially undercut the universal claim.
