The IAT (Implicit Association Test) is not without its flaws, obviously. But it's shown good reliability and validity in some cases at least, although it seems to suffer inadequate test-retest reliability at times (depending on the variables assessed, I guess).
Anyhow, there will always be some nuisance variables that need to be controlled for but are hard to disentangle, but it does seem like a lot of these variables have been taken care of, like the pairing order effect by randomising it with each participant.
