Summary:
Quote:
We began this article by arguing that many correlations reported
in recent fMRI studies on emotion, personality, and social
cognition are ‘‘impossibly high.’’ Correlations of this magnitude
are unlikely to occur even if one makes the (implausible) assumption
that the true underlying correlations—the correlations
that would be observed if there were no measurement error—
are perfect.
...
To sum up, then, we are led to conclude that a disturbingly
large, and quite prominent, segment of fMRI research on emotion,
personality, and social cognition is using seriously defective
research methods and producing a profusion of numbers
that should not be believed. Although we have focused here on
studies relating to emotion, personality, and social cognition, we
suspect that the questionable analysis methods discussed here
are also widespread in other fields that use fMRI to study individual
differences, such as cognitive neuroscience, clinical
neuroscience, and neurogenetics.
Thank for another great share, B19.
