The Phantom Cherry-pick

Would Sen. Bernie Sanders' Medicare For All plan save $2 trillion over 10 years on U.S. health care expenses?

Sanders and the left were on fire this week trying to co-opt a Mercatus Center paper by Charles Blahous. Sanders and others claimed Blahous' paper confirmed the M4A plan would save $2 trillion over 10 years.

PolitiFact checked in on the question and found Sanders' claim "Half True":

PolitiFact's summary encapsulates its reasoning:

The $2 trillion figure can be traced back to the Mercatus report. But it is one of two scenarios the report offers, so Sanders’ use of the term "would" is too strong. The alternative figure, which assumes that a Medicare for All plan isn’t as successful in controlling costs as its sponsors hope it will be, would lead to an increase of almost $3.3 trillion in national health care expenditures, not a decline. Independent experts say the alternative scenario of weaker cost control is at least as plausible.

We rate the statement Half True.

Throughout its report, as pointed out at Zebra Fact Check, PolitiFact treats the $2 trillion in savings as a serious attempt to project the true effects of the M4A bill.

In fact, the Mercatus report use what its author sees as overly rosy assumptions about the bill's effects to estimate a lower boundary for the bill's very high costs and then proceeds to offer reasons why the bill will likely greatly exceed those costs.

In other words, the cherry Sanders tries to pick is a faux cherry. And a fact checker ought to recognize that fact. It's one thing to pick a cherry that's a cherry. It's another thing to pick a cherry that's a fake.

Making Matters Worse

PolitiFact makes matters worse by overlooking Sanders' central error: circular reasoning.

Sanders' takes a projection based on favorable assumptions as evidence that the favorable assumptions are reasonable assumptions. But a conclusion one reaches based on assumptions does not make the assumptions more true. Sanders' claim suggests the opposite, that when the Blahous paper says it is using unrealistic assumptions the conclusions it reaches using those assumptions makes the assumptions reasonable.

A fact checker ought to point out whaten a politician peddles such nonsensical ideas.

PolitiFact made itself guilty of bad reporting while overlooking Sanders' central error.
