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

Is it true that Wrinkled fingers improve grip on wet objects?

Partly. Several studies report that water-induced finger wrinkling improves grip efficiency or speed when handling wet objects, while one large study found wrinkling did not improve dexterity in handling wet objects. The evidence is mixed on whether wrinkled fingers improve grip on wet objects.
