The hard work of science

A theory can be proved by experiment;

but no path leads from experiment to the birth of a theory.

- Manfred Eigen

Proposing new theories is the hard work of science. It requires insights and guts. The theory you propose will be proved wrong, since all theories are wrong. It is far easier to run another experiment. Experiments are usually a series of technical problems (e.g., How do we find subjects? How do we analysis the data?). It feels safe to correctly solve technical problems. It is harder to create the time and space to develop a new theory.
