Sivame ukuzwa ukuthi ukuxhumana nokuxhumana okuseduze kusisindisa ekucindezelekeni futhi kwenza ukuphila kube ngcono. Kuvele ukuthi abantu abasezingeni eliphezulu abakhaliphile abadingi ukuba nenqwaba yabangani ukuze bajabule.
Kudala okhokho bethu babehlala emiphakathini ukuze baphile. Namuhla, umuntu ubhekana nalo msebenzi futhi eyedwa. Lokhu kucabanga kwenze izazi zokusebenza kwengqondo u-Satoshi Kanazawa kanye no-Norman Lee ukuthi basebenzisane ukuze bathole ukuthi ukuminyana kwabantu kuzithinta kanjani izimpilo zethu. Futhi ngaleyo ndlela hlola i-"savannah theory".
Lo mbono uphakamisa ukuthi izigidi zeminyaka edlule, zibhekene nokuntuleka kokudla ehlathini lase-Afrika, izinkawu zathuthela endaweni enotshani. Nakuba ukuminyana kwabantu be-savannah kwakuphansi - umuntu oyedwa kuphela ku-1 sq. km. km, okhokho bethu babehlala ezindlini eziseduze zabantu abangu-1. “Ngaphansi kwezimo ezinjalo, ukuxhumana njalo nabangane nabalingani kwakubalulekile ukuze umuntu aphile futhi azale,” kuchaza uSatoshi Kanazawa noNorman Lee.
Abantu abahlakaniphe kakhulu mancane amathuba okuthi bachithe isikhathi esiningi bezijabulisa
Besebenzisa idatha evela ocwaningweni lwabantu baseMelika abangu-15 abaneminyaka engu-18-28, ababhali bocwaningo bahlaziye ukuthi ukuminyana kwabantu endaweni esihlala kuyo kuyithinta kanjani inhlalakahle yethu engokomzwelo nokuthi bayadingeka yini abangane ukuze bathole injabulo.
Ngesikhathi esifanayo, izinkomba zokuthuthukiswa kwengqondo kwabaphenduli zacatshangelwa. Izakhamizi zasemadolobheni amakhulu anabantu abaningi ziphawule izinga eliphansi lokwaneliseka kwempilo uma kuqhathaniswa nezakhamizi ezihlala ezindaweni ezigqagqene. Lapho umuntu egcina ukuxhumana nabantu abajwayelene nabangane bakhe, kulapho “inkomba yenjabulo” yakhe siqu iba phezulu. Lapha konke kwaqondana nethiyori ye-savannah.
Kodwa lo mbono awuzange usebenze nalabo abane-IQ yabo engaphezu kwesilinganiso. Abaphendula abanama-IQ aphansi bahlushwa ukuminyana ngokuphindwe kabili kunongqondongqondo. Kodwa ngenkathi behlala emadolobheni amakhulu akuzange kuthuse abantu abane-IQ ephezulu, ukuzijabulisa kwabantu akuzange kubenze bajabule. Abantu abanama-IQ aphezulu bavame ukuchitha isikhathi esincane sokuzijabulisa ngoba bagxile kwezinye, izinjongo zesikhathi eside.
“Inqubekelaphambili yezobuchwepheshe kanye ne-inthanethi izishintshile izimpilo zethu, kodwa abantu basaqhubeka nokuphupha ngasese ngemibuthano ezungeze umlilo. Abantu abanama-IQ aphezulu bahlukile, kusho u-Satoshi Kanazawa no-Norman Lee. “Zijwayelana kangcono nokuxazulula imisebenzi emisha eguqukayo, ziziqondise ngokushesha ezimeni nasezindaweni ezintsha. Yingakho kulula ukubekezelela ukucindezeleka kwamadolobha amakhulu futhi ungadingi abangane kakhulu. Bayakwazi ukuzimela futhi bajabule bodwa. ”
