The present paper investigates why certain adults are, or believe to be, more ironic than others. In particular, it tries to compare irony understanding and implementation to its subjective affective appraisal. The context is that of Polish-speaking adults and nonverbal intelligence determined with the Wechsler Adult Intelligence Scale-Revised-Polish versions (WAIS-R(PL), 2004). Female and male participants were assessed through a questionnaire in Study 1 and the performance quotient (IQ) was evaluated in Study 2 through performance subtests of the Wechsler Adult Intelligence Scale-Revised-Polish versions (WAIS-R(PL), 2004). The nonverbal intelligence scale was also processed. Irony and IQ resulted directly correlated. Gender was also taken into account in the analysis of the outcomes.
