Scientists found that ants count their steps to know how to get back to their nests. In one test they intercepted 84 ants that were turning back to their nests and cut all their legs 1 joint shorter. The ants didn't go far enough. In another test group they intercepted 75 ants and glued on extra leg segments to make their legs longer. Those ants past the nest. Is this experiment reliable?
What is yes, it is reliable?
159 total ants tested is pretty reliable, especially when similar results (not making it to the nest or going to far past the nest) is consistent. More ants and more varieties/colonies could make it more reliable
BTW. This is a real experiment/ published paper however the numbers are made up.
