SCIENTIFIC - high sci validity - base on objective, measurable and falsifiableevidence
studies that use gene mapping (location and distance) - identifiedspecificgenes (D2A1 + ADH1Bvariants) associated with increasedrisk for certainA
e.g. Tolstrup and Comings
explanation is wellrespected by wider scientific community, other explanations lackscientific rigour
DETERMINISTIC
implies, if you have a particulargeneticmakeup > inevitable - becomeA
problematic - ignoresrole of freewill and removespersonalresponsibility > someA feel - engaging in treatmentprogrammes is pointless, as recovery - beyondtheircontrol
explains why manyAstruggle to control their Bdespitewanting to stop
RE
Comings et al (96) = 48.7% smokers carry D2A1, comp 25.9% genpop
= 50.9% gamblers carry gene, comp 25.9% nong
Tolstrup et al (07) - sample, 9080men and women with ADH1Bdrankmore alc and higherrisk of alc
presence of variant - linked with risk of heavy drinking and alcamongwhite population (62%) and east asian population (24%)
support for explanation
