If you have not read Charles Murray's book "The coming apart of white America" it is worth the bother.
It's likely that since SES correlates with IQ that those most impacted within a specific demographic group by the shelter in place order will have lower IQs.
Keep in mind however that due to the Flynn effect being primarily on specialized abilities the thing differences may be less.
Also as Jordan Peterson has pointed out IQ and pro social behavior does not correlate. More importantly these correlations tell us nothing about individuals within in SES groups.
The real issue with the response to Civid 19 is the difference in how it has effected different SES groups. We live in a splintered society where higher SES groups are insulated from the consequences of their ideological predispositions. Something Victor Davis Hanson often talks about and Charles Murray notes.
Lower SES individuals that are working and not on government assistance are for the most part more likely to be "essential". The "deplorables" as it turns out are the foundation of not only our civilization but any civilization. While are coastal elites are not the idle rich they are functional similar or analogous to the petty nobility of 18th century France. It isn't surprising to see Nancy Pelosi saying let them eat ice cream. If we continue to ignore society's foundation the civilization may very well crack.
I would use Britain as an example of how failure to maintain a healthy productive class generating a strong economy has weaken their medical system. Very few new drugs come from Britain. Between 2001 and 2010 the U.K accounted for 16 new chemical entities why the U.S. accounted for 111. More importantly the model of encouraging small business in the U.S. has proven more effective than centralized government in innovation and economic robustness. What Britain has basically done is export the misery of the working class and pollution to China by way of the Banksters in the city of London. While a strong welfare and government medical system has reduced misery it's very poor at producing necessary reserves. Before the out break Britain had 6 ventilators to the United States 33 per hundred thousand people.
Not that complicated.
The R-nought value for SARS COV2 is well-known now. Its 5.7 over 2.5 days. If you can do the math, you know that over 10 billion people would be infected in 5 weeks. So not only did the Chinese have zero chance of containing it by the time they realized it was a problem, the World was fully infected before even being aware of the existence of the problem in China. Dr Li Wenliang announced the first case to have been known 17 November. Trump closed down flights to/from China and Europe on the 31st of January, while Democrats were celebrating his impeachment in the House, 10 weeks after the first case was known, while WHO was still claiming no transmission to human to human.
99% of COVID-19 deaths are smokers or those with serious pre-existing conditions. That's why Italy has more victims and Sweden fewer. Those of us not in that group are at far more danger of getting killed driving to the grocery store than from the virus. Social distancing was always irrelevant. And while the infectiousness of SARS COV2 is four times the Spanish Flu, the mortality rate is almost certainly less than the flu. See "Multiple Conditions Increases Risk."

The media has been nearly bankrupt because it is so mistrusted by the public, and badly needed a sensational story, so they made the most of it as a matter of their survival. And the New York Times proudly reported that 87% of the media are Democrats. The public was only too happy to panic on command, and leadership had no choice but to respond accordingly.
Tell your leadership that this ends now.
And the New York Times is best used as toilet paper, not news.
