I just wish I could reliably tell which economics were empirical and not 
political...

Math Has Become Politicized

Russ Roberts on Paul Krugman:

Krugman is a Keynesian because he wants bigger government. I’m an 
anti-Keynesian because I want smaller government. Both of us can find evidence 
for our worldviews. 

Paul Krugman, responding:

Russ Roberts may choose his economic views because they support his political 
prejudices. I try not to. Maybe I sometimes fall short — but I try to analyze 
the economy as best I can, never mind what’s politically convenient […]

Roberts’ comments perfectly exemplify what I’ve been thinking for a while now. 
As I see it, there are two types of economists: political and empirical. 
Political economists start with their political beliefs and then “find 
evidence” to back up their ideologies. Empirical economists look at the numbers 
objectively and then figure out what’s best. They don’t don’t start with 
pre-drawn conclusions (e.g. “smaller government”). They start with an open mind 
and aren’t afraid to recommend an economic policy that runs antithetically to 
their political beliefs.

That we have certain economists who put politics ahead of math isn’t a problem 
in and of itself. The problem is that most of our politicians surround 
themselves with like-minded political economists. Now we’ve come to the point 
that when a group of empirical economists publishes numbers that don’t align 
with a politician’s political views, said politician derides the organization 
as a “reactionary socialist institution”.

If we want to get out of the mess we’re in, numbers need to come first — not 
politics.
