Nomothetic causal explanations focus on objectivity, prediction, and generalization. Cov txheej txheem rau kev sib raug zoo ntawm nomothetic causal yuav tsum muaj kev sib raug zoo plausible thiab nonspurious; thiab qhov ua rau yuav tsum ua ntej qhov tshwm sim hauv lub sijhawm.
Nimno lub ntsiab lus piav qhia yog dab tsi?
Qhov sib txawv, cov lus piav qhia nomothetic nrhiav kev piav qhia ib chav ntawm cov xwm txheej lossis cov xwm txheej tsis yog qhov xwm txheej tshwj xeeb lossis xwm txheej… los yog tib neeg, lawv zoo li tsis meej, tsis tiav, thiab tsis meej.
Puas yog qhov kev piav qhia nomothetic causal yog txiav txim siab?
Idiographic piav qhia yog qhov kev txiav txim siab, tsom mus rau qhov ua rau muaj qhov tshwm sim tshwj xeeb tshwm sim lossis dab tsi ua rau muaj xwm txheej hloov pauv. Raws li nyob rau hauv nomothetic piav, idiographic causal piav qhia muaj peev xwm muaj counterfactuals, los ntawm kev sim txheeb xyuas seb yuav tshwm sim yog tias muaj xwm txheej sib txawv.
3 yam uas yuav ua rau muaj qhov tshwm sim yog dab tsi?
thawj peb yam uas feem ntau suav hais tias yog qhov yuav tsum tau txheeb xyuas qhov ua rau muaj txiaj ntsig: (1) kev koom tes ua pov thawj, (2) qhov tseem ceeb ntawm lub cev ntawm qhov sib txawv ntawm kev ywj pheej, thiab (3) tsis muaj txiaj ntsig. Koj yuav tsum tsim peb qhov no los thov kev sib raug zoo.
Peb yam xwm txheej twg yog dab tsi rau qhov kev sim tshuaj ntsuam xyuas randomized rau tus kws tshawb fawb kom pom qhov ua rau?
Nyob rau hauv cov ntsiab lus, ua ntej cov kws tshawb fawb tuaj yeem txheeb xyuas qhov kev sib raug zoo ntawm ob qhov sib txawv, peb lub ntsiab lus tseem ceeb: kev sib koom ua lag luam, kev txiav txim siab tsim nyog, thiab tsis muaj kev xavTom qab peb cov xwm txheej no tau ua tiav lawm, ob yam tseem ceeb kuj tseem ceeb: cov txheej txheem ua rau thiab cov ntsiab lus.

Vim li cas lub hli ntsais? Thaum qhov chaw txav mus, gases uas cuam tshuam lub hnub tuaj yeem khiav tawm ntawm lub hli sab hauvQhov no yuav piav qhia txog qhov tshwm sim luminous, qee qhov uas nyob ntev li teev.
