Let's Gather Some Data, Shall We?

The story goes that, upon hearing of Richard Nixon's election triumph, a resident of New York's tony Upper East Side exclaimed "But how could that happen?  Everybody I know voted for McGovern!"

Usually attributed to film critic Pauline Kael, it's an example of the logical fallacy known as hasty generalization: drawing an overbroad conclusion based on a statistically insufficient sample. 

From the Wall Street Journal:

"In reality, Kael was more self-aware than that. What she actually said, as reported by the Times in December 1972, was: "I live in a rather special world. I only know one person who voted for Nixon." But you see how the fallacy works: By her own account, Kael led a parochial life, seldom venturing outside her "special world." If she had mistaken her circle of acquaintances for a representative sample of Americans, she would have been mystified by the election outcome."


To a certain extent, we all live "parochial lives."  We can't do everything, see everything or know everyone.  But successful marketers and strategists maintain the self-awareness to recognize the trap and say "Hmm.  Maybe we need to gather some data here."

Michael Porter On Health Care Reform

Michael Porter, writing in the New England Journal of Medicine, proposes "A Strategy For Health Care Reform - Toward A Value-Based System." His proposals are fundamental, lucid and right-on, meaning they're sure to be opposed by some parties to the debate, the so-called "Yes, but..." crowd. Most important, in my opinion, is this: "... electronic medical records will enable value improvement, but only if they support integrated care and outcome measurement. Simply automating current delivery practices will be a hugely expensive exercise in futility. Among our highest near-term priorities is to finalize and then continuously update health information technology (HIT) standards that include precise data definitions (for diagnoses and treatments, for example), an architecture for aggregating data for each patient over time and across providers, and protocols for seamless communication among systems. "Finally, consumers must become much mor

Being Disrupted Ain't Fun. Deal With It.

Articles about disrupting healthcare, particularly those analogizing, say, Tesla's example with healthcare's current state, are frequently met with a chorus of (paraphrasing here) "Irrelevant! Cars are easy, healthcare is hard." You know, patients and doctors as examples of "information asymmetry" and all that. Well, let me ask you this: assuming you drive a car with a traditional internal combustion engine, how much do you know about the metallurgy in your car's engine block? I'll bet the answer is: virtually nothing. In fact it's probably less than you know about your own body's GI tract. Yet somehow, every day, us (allegedly) ignorant people buy and drive cars without help from a cadre of experts. Most of us do so and live happily ever after (at least until the warranty expires. Warranties...another thing healthcare could learn from Tesla.) Now, us free range dummies - impatient with information asymmetry - are storming healthcare

My Take On Anthem-Cigna, Big Dumb Companies and the Executives Who Run Them

After last Friday's Appeals Court decision, Anthem's hostile takeover of, er, merger with Cigna has but a faint pulse. Good. Unplug the respirator. Cigna's figured it out but Anthem is like that late-late horror show where the corpse refuses to die. Meanwhile, 150 McKinsey consultants are on standby for post-merger "integration" support. I guess "no deal, no paycheck..." is powerfully motivating to keep the patient alive a while longer. In court, Anthem argued that assembling a $54 billion behemoth is a necessary precondition to sparking all manner of wondrous innovations and delivering $2.4 billion in efficiencies. The basic argument appears to be "We need to double in size to grow a brain. And just imagine all those savings translating directly into lower premiums for employers and consumers."  Stop. Read that paragraph again. Ignore the dubious "lower premiums" argument and focus on the deal's savings. $2.4 billion saved
