Well, both really. Economics as objective science is an ugly sister (didn’t I read about some guy trying to have economics drummed out of the “science” academy altogether?) I mean, if this is so scientific and objective, how come a firm consensus on any economic topic is so elusive?
I am suspicious anytime someone says the consensus of economic experts is clear about anything. I will certainly agree that trade is good, and likely, the more the better. But does everybody mean precisely the same thing when they say “free trade”? How many economists signed on to the “Laffer Curve”, which purports that lowering taxes increases government revenue because the economy booms? Were they drummed out?

I probably wouldn’t agree with Renob on the color of the sky at midnight, but here, he is quite right. The free trade consensus is all but universal. Exactly how much “free trade” and under what circumstances is still debated, of course. but then again, do we really know how much iron should be in your diet?
The above is not really a fair way to characterize either economics or any other science. First, there is a great deal of consensus in economics about a large number of topics. The consensus is so vast I almost do not even know where to begin. The fact that there is a great deal of dispute on key questions invalidates economics no more than the lack of unity between classical and quantum mechanics undermines physics.
Economics is a science because it is a field of inquiry that strictly follows the scientific method. Theory. Hypothesis. Test, either classical or Bayesian.
The “Laffer Curve” is a neat little model. Reagan loved it because, well, you could draw it on a napkin. It was simple, it can be communicated easily to the masses, and it requires no more than 8th grade math to prove, let alone understand cursorily. It is a logical illustration. Its limitations are well known and well understood. The fact that it drove policy is a function of the administration that latched onto it like an anemic urchin on a DD tit.
