I know I shouldn't feed the trolls, but it deserves to be said.
In no way is String Theory anything like Phrenology. Trying to develop a model that unites both the large scale and the small scale is incredibly difficult. Quantum mechanics and relativity are complex enough without trying to unify them. String theory and super-symmetrical models have a basis in advanced mathematics, but the question is whether or not the model matches the immensely complex reality.
Even if it doesn't work out, studying the problem advances our knowledge of the known universe and modelling it in mathematics. That's how science works, you make a hypothesis and you attempt to test it and then you reform your hypothesis. The current problem right now is finding a way to test it. A failed hypothesis is not something to laugh at, because what you learn from that failure helps you forms a new and more accurate model.
