Ingabe umbala wepuleti lakho unomthelela ekutheni udla kangakanani? Ucwaningo olusha lukaDkt. U-Brion Vansilk no-Koert van Itteram babonise ukuthi umehluko wombala phakathi kokudla nezitsha kudala inkohliso yokubona. Emuva ngo-1865 ososayensi baseBelgium baveza ukuba khona kwalomphumela. Ngokwalokho abakutholile, lapho umuntu ebheka imibuthano egxilile, indilinga yangaphandle ibonakala inkulu futhi indilinga yangaphakathi ibonakala incane. Namuhla, isixhumanisi sitholakele phakathi kombala wezitsha nosayizi wokuphakela.
Ukwakhela phezu kocwaningo lwangaphambilini, u-Wansink kanye no-van Itteram benze uchungechunge lwesivivinyo ukuze baqonde ezinye izinkohliso ezihlobene nombala nokuziphatha kokudla. Bafunda ithonya lombala wezitsha hhayi kuphela, kodwa futhi ngokuphambene nendwangu yetafula, ithonya lobukhulu bepuleti ekunakekelweni nasekucabangeni kokudla.
Ngokuhlolwa, abacwaningi bakhethe abafundi basekolishi enyakatho yeNew York. Abahlanganyeli abangamashumi ayisithupha baye e-buffet, lapho banikezwa khona i-pasta ne-sauce. Abafundi bathola amapuleti abomvu namhlophe ezandleni zabo. Isikali esifihliwe sasigcina umkhondo wokuthi kungakanani ukudla abafundi abakubeka epuletini labo. Imiphumela iqinisekisile i-hypothesis: i-pasta ne-tomato sauce epuleti elibomvu noma nge-Alfredo sauce epuleti elimhlophe, ababambiqhaza babeka i-30% ngaphezu kwesimo lapho ukudla kuqhathaniswa nezitsha. Kodwa uma umphumela onjalo ukhona ngokuqhubekayo, cabanga ukuthi sidla ngokweqile kangakanani! Kuyathakazelisa ukuthi umehluko wombala phakathi kwetafula nezitsha usiza ukunciphisa izingxenye ngo-10%.
Ngaphezu kwalokho, uVansilk no-van Itteram baphinde baqinisekisa ukuthi uma ipuleti lilikhulu, okuqukethwe kwalo kubonakala kuncane. Ngisho nabantu abanolwazi abazi ngama-optical illusions bawela kulokhu kukhohlisa.
Khetha izitsha ngokuya ngomgomo wokudla okuningi noma okuncane. Uma ufuna ukwehlisa isisindo, phakela isidlo kupuleti lokuqhathanisa. Ingabe ufuna ukudla imifino eminingi? Yiphake epuleti eliluhlaza. Khetha indwangu yetafula efana ne-dinnerware yakho futhi i-optical illusion izoba nomthelela omncane. Khumbula, ipuleti elikhulu iphutha elikhulu! Uma kungenakwenzeka ukuthola izitsha ezinemibala ehlukene, beka ukudla kwakho kumapuleti amancane.
