If "subliminal biases" is a reference to "Implicit association" and the IAT-- IAT has lost it's scientific footing. The problem with it is that: Just because people have Implicit Associations doesn't predict that they will act in biased way.
> Implicit association tests probably don’t work (1, 2, 3, 4). That is, people who have “implicit racial biases” according to the tests are not more racist in everyday life than people who don’t. If this were true – and if it reflected a general failure of implicit racial biases to affect explicit actions – it’s hard to overestimate how much it would change psychology. We wouldn’t have to worry about how the wrong character on TV would accidentally bias people toward having certain stereotypes. We wouldn’t have to worry about subconscious racism affecting hiring decisions even among people who are trying hard to be fair and neutral.
