Philosophy of science is as useful to scientists as ornithology is to birds.
— Richard Feyman
There is an interesting flock of bird concepts in epistemology, philosophy of science and risk theory:
Despite decades of intensive ornitho-epistemological research, the bird-ness of Rabbitduck  could not been firmly established yet. Every time we think we nailed it, the the rabbit-ness wins over and we are back to square one. More research is needed.
 We are sad to report, but there is still a small, but very vocal part of our research community, that insists on the clearly ignorant “Duckrabbit” nomenclature.
We also don’t subscribe to the wishy-washy, cheap consensus of the Copenhagen interpretation, that claims that the creature is both a rabbit and a duck.
