person made or was aware of making that conscious choice.
Noticing the decision we ourselves have made appears to happen
quite a long way down the processing hierarchy and as the result
of processes to which we don’t have conscious access.

Antonio Damasio, professor of neurology at the University of
Iowa, describes a study he conducted with an individual, David,
with severe learning and memory defects.

David had extensive
damage to both temporal lobes, was incapable of learning any new
fact, and could not recognize anyone, nor recall any part of their
appearance, voice, or things they may have said. To explore whether
the brain required a link between consciousness and emotions,
Damasio created a situation where David experienced three distinct
types of interaction from three different people over several days:
one was consistently positive, one neutral, and one unpleasant. Later
David was shown sets of photographs, each containing one of the
people with whom he’d had the interactions, and asked whom he
would go to for help and who was his friend. Despite not being
able to remember ever meeting the people or anything about them,
David selected in a way that proved he had factored in his experi-
ence from the previous day, yet he was able to provide no basis for
his selections. This extreme case lends further support to the notion
that we don’t need our conscious processes to act effectively. As
Moll showed, when our conscious faculties are working properly,
we’re adept at creating a justification that works for us.
Our selective attention is continually screening out a huge
amount of information but, as I have explained, that doesn’t mean
that this information isn’t being processed. Quite the opposite: in
order to screen it out we must first receive it. Studies such as those
by Bargh and Pietromonaco show that, while we are not consciously
processing it, our unconscious mind can be changed by what passes
through it, leaving us with no realization that such a change has taken
place and certainly no ability to report it accurately after the event.
The unconscious mind appears to operate as a first-stage pat-
tern checker, the first, and sometimes only, stage in the processing
and reacting chain. However, since people have no direct access to
the references it’s using, consumer research respondents are unlikely
to report accurately its role in their decision making. Consequently,
