Kalmar masu hankali tana nufin wasu gungun mutane masu ilimi da ilimi musamman a fagen ilimi ko al'adu, kuma galibi suna shiga cikin yada wadannan tunani ga al'umma gaba daya. Ana amfani da kalmar sau da yawa wajen bayyana hazikan al’umma ko al’ada, wadanda galibi marubuta ne, masu fasaha, masana ilimi, ko wasu masu fada aji masu tasirin al’adu ko siyasa.
