the Eklund study does point at a much bigger problem facing science: how it deals with the fact that a certain proportion of studies are always flawed.

in 2009, some researchers put a dead salmon into an fMRI scanner, just to see what would happen. To their surprise parts of the brain lit up, as if the dead fish were “thinking.”
What Eklund’s studies have shown, however, is that the real rate of false positives can often be far higher than 5%.
the flaws in fMRI are a good example of how scientists are tackling one of the biggest problems the discipline is currently facing: that of making experiments reproducible.
