The Policygenius Life Insurance Price Index March 2022



Smokers and nonsmokers alike saw minor increases in life insurance prices from February to March. The biggest increase in average monthly premiums, of 3.26%, was seen by 25-year-old smokers buying $250,000 in coverage, and only amounts to $1.08 more a month. Most other demographics saw price increases that were less than 1%.

The minor pricing changes shouldn’t have much impact on consumers’ wallets, especially as insurers continue to compete for business. Although people buying life insurance in March may be paying a few cents more on average, most insurers are implementing pricing changes to win business rather than repel it.

Table 2 fallacy and stepwise regression



One problem may be the way we teach statistics to data scientists and public health professionals. Multivariable regression is often mistaken for a silver bullet that magically controls away confounding for all variables at once, as long as no confounder is left out. This is what statisticians call the “Table 2 fallacy,” because the adjusted effect sizes in a multivariable model are so often reported in Table 2. Many medical professionals learn to read research articles critically for understanding without ever having been introduced to the Table 2 fallacy.

Confounding is often taught as a purely mathematical concept, but that misses the point. Throwing a large set of variously interrelated variables into a big stepwise regression model might be expected to work, if all you know about confounding is that you should “never leave a confounder out” of your analysis.
