Didn't neuroscience some big scandals about bad statistics and overstating their findings (in addition to normal issues like replication)? Look up at least the "dead salmon study" (hint: it's related to fMRI, and you can probably guess its conclusions from its nickname). The "Voodoo Correlations" and "Cluster Failure" papers are also a bit eye-opening.

In general we (humans) need to be humble about the limitations of our knowledge about how we function, it's an insanely complicated problem.
