Abstract:There seem to be two kinds of nonconservers—those who think their response might change on another occasion and those who think their response would always be the same. After training in conservation, the former (called nonconservers without necessity) show no detectable gains in conservation, while the latter (called nonconservers with necessity), surprisingly, show significant gains in conservation.In the present study, nonconservers with necessity were more likely than the nonconservers without necessity to think the classic conservation arguments (e.g., identity, negation, and compensation) were good and correct reasons and that the typical nonconservation reasons were poor and wrong.In sum, the nonconservers who can support their conclusions with the deductive force of necessity, even though they are wrong in their conclusion, appear to be more developmentally advanced than other nonconservers who do not offer necessity as part of the justification for their nonconservation conclusion.
