The IRS publishes a standardized mileage rate. This isn’t a very accurate description of just the simple dollar costs of commuting by car, but it’s at least a number that actually means something. Multiplied by your commute multiplied by times that commute is traveled gives you some idea of the costs of the commute.
That it presents somewhere in the order of a 100 USD to 300 USD in monthly additional costs for a ten mile difference in travel time to you work is almost certainly an underestimate, but it’s really easy to forget these sort of tradeoffs when looking at a home to buy or rent or comparing different job offers.
The math for public transportation is a lot harder, and generalizes less (one person’s relaxing train ride is another person’s battle with nausea and agoraphobia). It’s still a useful place to start.
I would expect that even as a fairly squishy pro-abortion Westerner (incredibly discomforted with the procedure but even more discomforted by the actions necessary to ban it), I’m likely to underestimate the health risks of even contragestives, and significantly underestimate the health risks of abortion procedures. Discussion in these circles also overstates the effectiveness of conventional contraception and often underestimates the number of abortions performed yearly. The last number is probably the easiest to support through evidence, although I’d weakly expect it to ‘fool’ smaller numbers of people than qualitative assessments.
I’m also pretty sure that most pro-choice individuals drastically overestimate its support by women in general—this may not be what you’re looking for, but the intervals (40% real versus 20% expected for women who identify as “pro-life”) are large enough that they should show up pretty clearly.
