Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Mashoko okuti "kusarura kusimbisa" akatangwa nenyanzvi yezvepfungwa yokuEngland Peter Wason. Mukuedza kwake kwokutanga kwakabudiswa muna 1960 (iyo isingatauri shoko rokuti "kusarura kwokusimbisa"), akatambudza vatori vechikamu kuti vazivise mutemo unoshanda kune katatu kwenhamba. Pakutanga, vakaudzwa kuti (2,4,6) inowirirana nomutemo. Vatori vechikamu vaigona kugadzira zvitatu zvavo uye muongorori akavaudza kana zvitatu zvose zvaienderana nomutemo wacho. Nepo mutemo chaiwo wakanga uri "chero nhevedzano inokwira", vatori vechikamu vakava nechinetso chikuru mukuuwana, kazhinji vachizivisa mitemo yakanga yakanyatsorondedzerwa, yakadai sokuti "nhamba iri pakati ndiyo yepakati yeyokutanga neyokupedzisira". Vatori vechikamu vairatidzika kuva vaidzidza mienzaniso yakanaka bedzi - zvitatu zvaiteerera mutemo wavo wokufungidzira. Somuenzaniso, kudai vaifunga kuti mutemo wacho waiti, "Nhamba imwe neimwe yakakura kaviri pane yakatangira", vaizopa katatu kaizoenderana nomutemo uyu, zvakadai se (11,13,15) pane katatu kaizouputsa, zvakadai se (11,12,19). Akatsanangura zvaakawana sokuratidza kufarira kusimbisa pane kunyengera, nokudaro shoko rokuti "kusimbisa rusaruro". Wason akashandisawo kusarura kwekusimbisa kutsanangura migumisiro yebasa rake rokusarudza kuedza. Mubasa iri, vatori vechikamu vanopiwa mashoko asina kukwana pamusoro pezvinyorwa, uye vanofanira kutsanangura mamwe mashoko avanenge vachida kuti vaone kana mutemo une zvaunosungirwa ("Kana A, ipapo B") uchishanda. Zvakawanikwa kakawanda kuti vanhu vanoita zvakashata pamhando dzakasiyana-siyana dzekuedza uku, kazhinji kacho vachiregeredza ruzivo runogona kupokana nemutemo. Zvisinei, pepa ra1987 rakanyorwa naKlayman naHa rakataura kuti kuedza kwaWason kwakanga kusina kuratidza kusarura kune kusimbiswa, asi panzvimbo pezvo maitiro ekuita kuti miedzo ienderane nefungidziro yekushanda. Vakaidana kuti "nzira yokuedza inobvumikisa". Nzira iyi muenzaniso we heuristic: nzira pfupi yokurangarira isina kukwana...  Mubvunzo: Chii chinogadzira mashoko mumwero wakasiyana?
