Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Putanga: Ko te kupu "tohu whakamana" i hangaia e te tohunga hinengaro Ingarihi a Peter Wason. I roto i tana whakamātautau tuatahi i whakaputaina i te tau 1960 (kaore e whakahua i te kupu "tohu whakatuturutanga"), i werohia e ia nga kaiuru ki te tautuhi i tetahi ture e pa ana ki nga tokotoru o nga tau. I te tīmatanga, i korerotia ki a rātau ko te (2,4,6) e ōrite ana ki te ture. Ka taea e ngā kaiuru te whakaputa i ō rātou ake tokotoru, ā, ka whakaaturia e te whakamātautau ki a rātau mēnā e ōrite ana ia tokotoru ki te ture. Ahakoa ko te ture tūturu ko "tetahi raupapa piki ake", he nui te uaua o ngā kaiuru ki te kimi i a ia, i te nuinga o te wā e pā ana ki ngā ture i tino tika ake, pēnei i te "ko te tau waenganui ko te toharite o te tuatahi me te whakamutunga". I te āhua nei i whakamātauria e ngā kaiuru ngā tauira pai anake <unk> e toru ngā tauira i ngohengohe ki tā rātau ture whakapae. Hei tauira, ki te whakaaro ratou ko te ture, "Ko ia tau e rua te nui ake i tona mua", ka tukuna e ratou he toru e uru ana ki tenei ture, penei i te (11,13,15) kaua ki te toru e takahi ana, penei i te (11,12,19). I whakaaetia e Wason te whakakorenga, e ai ki te whakamatautau putaiao o te whakapae he tino ngana ki te whakakorekore. I whakamāramatia e ia ana hua hei whakaatu i te manakohanga mo te whakaū i runga i te whakaraerae, nō reira ko te kupu "tohu whakaū". I whakamahia hoki e Wason te whakakahoretanga whakaū hei whakamārama i ngā hua o tana whakamātautau mahi whiringa. I roto i tēnei mahi, ka hoatu ki ngā kaiuru he mōhiohio ā-wāhi mō tētahi huinga ahanoa, ā, me whakamārama he aha ētahi atu mōhiohio e hiahiatia ana e rātau hei whakamārama mēnā ka pā mai tētahi ture herenga, kāore rānei ("Mēnā A, kātahi ko B"). Kua kitea i nga wa katoa he kino te mahi a nga tangata i runga i nga momo momo whakamatautau, i te nuinga o nga keehi kaore i te aro ki nga korero ka taea te whakakore i te ture. Heoi, i kii tetahi pepa 1987 na Klayman me Ha kaore nga whakamatautau a Wason i whakaatu i te whakaaro ki te whakaū, engari ko te tikanga kia rite nga whakamatautau ki te ariā mahi. I kīia tēnei e rātau ko te "rautaki whakamātautau pai". He tauira tēnei rautaki o te heuristic: he hātepe whakaaro kāore i tino tika...  Pātai: He aha te mea e whakaputa mōhiohio ana i ngā rahinga rerekē?
