All bats are blind and rely entirely on echolocation to navigate.

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 bats are blind and rely entirely on echolocation to navigate?

No. Multiple reference and peer-reviewed sources state that bats are not blind, and several note that bats use echolocation to navigate in darkness. The claim that all bats are blind and rely entirely on echolocation is contradicted by sources explicitly denying bat blindness.
