Critics such as Gerd Gigerenzer and Ralph Hertwig criticized the Linda problem on grounds such as the wording and framing. The question of the Linda problem may violate conversational maxims in that people assume that the question obeys the maxim of relevance. Gigerenzer argues that some of the terminology used have polysemous meanings, the alternatives of which he claimed were more "natural". He argues that the meaning of "probable" ("what happens frequently") corresponds to the mathematical probability people are supposed to be tested on, but the meanings of "probable" ("what is plausible" and "whether there is evidence") do not. The term "and" has even been argued to have relevant polysemous meanings. Many techniques have been developed to control for this possible misinterpretation, but none of them has dissipated the effect.
