> Sensitivity analyses on a representative subsample of the cohort observed only small attenuation of the estimated effect of intelligence (by 10-26%) after adjustment for potential confounders, including three indicators of childhood socioeconomic status. In a replication sample from Scotland, in a similar birth year cohort and follow-up period, smoking and adult socioeconomic status partially attenuated (by 16-58%) the association of intelligence with outcome rates.
Poor people eat worse food; don't get as much exercise; and smoke more.
You can predict average life expectancy by post-code, and that's based on socio-economic factors.
How is choosing to smoke more an inequality?
Answers include availability, lack of availability of healthier alternatives, targeted marketing, being missed by anti-smoking campaigns, and peer group influences.
While smoking may be a personal choice, it is not made in a vacuum.

"Men in the least deprived areas of Scotland may live 12.5 years longer than those in the most deprived areas while women in the least deprived areas could expect to live 8.5 years longer than those in the most deprived."

And health (and all other) outcomes are strongly affected in the UK by geography. On average you'll live in Sussex nearly a decade longer than in Cowdenbeath. In Glasgow as late as the mid-1980s the average male life expectancy was 58 years, and then Scotland had the shit kicked out of it, on purpose, for twelve years, by the 1979 Thatcher government. Cuts in healthcare were inflicted disproportionately-severely on places which did not vote for the Conservatives, and nowhere were they more severe than central Scotland and south Wales.
Nothing you say contradicts the parent’s post. So ‘false’ is incorrect as well as obnoxious.
> In the absence of individual level data on socioeconomic status in the full SMS1947, we used school attended as a proxy measure to adjust for potential confounding by background socioeconomic status. A Scottish cohort study has shown that primary school has moderate correlation with paternal social class.
