Scientific consensus is rarely wrong.

There have been 3 major cases in the 20th century that I'm aware of where well-established theories turned out to be wrong.

1) Plate tectonics (dismissed until 1962)

2) The Bohr model of the atom, confirmed by the colours of light absorbed and emitted by ionised helium - which turned out to be wrong

3) The Sommerfeld extension of Bohr's model.

Both (2) and (3) were thought to be correct because they gave predictions correct to 4 decimal places. This turned out to be a co-incidence(!!) and their theories turned out to be wrong and replaced by Dirac's model.

Given the amount of science done in the 20th century, I think that's a pretty good record.
