Linguistic anthropologists question the position dominant in linguistics., psychology and cognitive science with regard to the extent of universal concepts because: Answer a. They are obstinate and refuse to be persuaded by empirical evidence. b. Even in domains such as space, where there substantial physical, environmental, and cognitive universals that constrain linguistic variability, there are still huge differences in how languages encode spacial relationships. c. They want to make their mark as innovative thinkers, and challenging established views is a very good way to do it.
