David Strom, writing on Facebook, sums up what I’ve been wanting/trying to say for much of this past 23 months:
Follow the science is a bullshit phrase, not because science itself is bullshit, but because science at best can only provide input and data on what are not scientific questions.
Science is a branch of knowledge seeking. It is not equipped to provide answers to what are in fact judgment calls. Public policy is at its root about making judgement calls–weighing risks and rewards, costs and benefits, and of course balancing competing rights and goods.
And in fact, no actual scientist believes that the scientific method is, in and of itself, superior to the other methods of seeking knowledge: history, logic, math, philosophy, and so on . They’re all just different tools to similar ends.
Science can help us better understand risks and rewards (when done well, with good data, and the right questions), but it can’t help us weigh those and come up with a “right” answer. If you have ever had a difficult conversation with a doctor you understand this. Doctors give you information upon which you make medical decisions, but in the end they ask you what you want to do based upon your own set of values.
When somebody tells you to “follow the science” they aren’t just making claims about what the science say (and in many cases it isn’t clear), but also to accept their values about how to weigh the costs and benefits.
Consider this extreme example of how important values are in making judgements about behavior (not a public policy example):
Alex Honnold is the world’s best “free solo” climber, and is admired by millions for his skill and grace. He is also, by any measure that values survival above all else, utterly insane. This is true of extreme athletes in general.
Science can tell us nothing about whether what he is doing is admirable or is just off his rocker, but if you watch any interview of him he seems perfectly rational–he just values preservation of his own life as less important than the things he gets from performing his craft.
It’s no different for a ballet dancer or football player, who both sacrifice their body and endure horrible pain to create their art/sport. They balance the risks and rewards based upon their own judgement of what is important. And obviously the answers vary by what individuals value most.
I’m going to emphasize this next bit:
Public policy exists in that same realm, although on a different scale. And public policy in a pluralistic society means that decisions about such matters are made with an eye to balancing the judgments of millions of people and finding artful compromises that garner enough support to be maintained. It’s why we have elections.
“Follow the science” is nothing more than a bullshit way to tarnish the values of people who have different visions of the good society. Science doesn’t speak to values and morals. Ask Josef Mengele. Science is just one of several means to get knowledge. A useful way. But no scientist can use it to tell you whether Monet is a great artist or not.
And yet we have bred a generation and change that believes science…
…no, conclusions given by people in real or rhetorial lab coats = morality.
