Tali
Sharot, professor of cognitive neuroscience at the department of experimental
psychology at University College London, is the author of the book The
Influential Mind: What the Brain Reveals about Our Power to Change Others. I
found this to be a very informative text which revealed tons of new information
about the way our brains work. Tali Sharot uses her academic research findings
as well as real life everyday examples to effectively communicate the workings
of our brain. For individuals who consider themselves with a curious mind, this
book should be a staple in your bookshelf as it can be full of profound
realizations, some of which may have already dawned on you prior.
Chapter
1 is essential in understanding the entire book as it introduces the term “priors”.
The title of chapter one is Does Evidence Change Beliefs? (Priors). The term prior refers to the views or beliefs
an individual already holds in his or her own brain. Tali continues to explain
how priors have an influence on the way a person views data that is presented
to them. The assumption she makes is that data presented will have a positive,
or perspective changing effect on an individual and force them to consider that
they might be wrong in their own assumptions or beliefs about the world. But
surprisingly, the opposite is true. It seems that the priors will have the
effect of dismissing the data or evidence as not true if it does not align with the prior belief. One other peculiar instance
Tali mentions is that based on her research, generally the more intelligent a
person is the more likely they will double down on their priors. Tail’s
assumption, and my own assumption, would be that the more intelligent a person
is, the more accepting of facts and evidence that person would be in analyzing
the challenging data. The conclusion of this chapter seems to be that evidence
is much more persuading when it is already in-line with an individuals own
worldview.
Chapter
3 is titled Should you Scare People into Action? (Incentives). Now,
before I had read this book, I was of the opinion that scaring or shaming people
into change is wrong and generally will not work. However, I did not know the
reason why if someone pressed me to explain. Luckily Tali Sharot was able to concretely
explain and show why scaring into action will not produce the desired effect.
She mentions New York state researchers who are tasked with studying the rates
of hand sanitization and installing techniques in order to actively increase
the complying of proper hand sanitization close to 100% for all staff. The case
study took place in an ICU in the north eastern United States At first, cameras
and sensors were installed with the staff’s knowledge to see is hand washing
rates increase. This proved to be not enough at first in order to enact the desired
change. This led to an electronic board which rewarded and gave immediate
positive feedback for each time an employee at the ICU complied with the hand sanitization
efforts installed at the hospital. Tali mentions that in order to enact an
action it is more important to reward incentives and provide positive feedback
when applicable. This will in turn increase the rate of compliance, with most
things not just hand washing although this was one of the main examples used in
this chapter.
The final chapter I want to discuss before wrapping this up is chapter 6
as I thought this to be one of the more interesting chapters covered in the
entire book. It is given the title of What Happens to Minds Under Threat?
(State). Tali Sharot explains how stress and intimidation can affect our
behavior. One parallel I would like to draw from this chapter to our lectures
is the term tonic immobility. I believe tonic immobility is a direct effect of
what can happen to our brains when we face stress. Tonic immobility refers to
the state of freezing in a dangerous situation. One scenario in this chapter I
thought was worth mentioning was the part where Tali Sharot discusses the man
who happened to incite an intentional mass panic by just running down the street
acting like something was terribly wrong. It is important to note this was just three days after the infamous 9/11 attack and in New York city. For Tali and the onlookers of this scenario,
they assumed the man was under threat from something immense and if he is running hurriedly then
surely the threat may be able to also affect the onlookers. This led to a small
state of mass hysteria that would not have likely happened had the stress and fear of the prior attack was not still ingrained in their psyche. I like to imagine I would not be too motivated by stress as to start sprinting
away from nothing, in a business suit most likely considering New York's immense business professional sector, in broad daylight. However I am sure those
who engaged in the panic running would have thought the same that morning when asked if stress or fear controlled them that much. The conclusion
of this chapter in my opinion is to recognize that stress and perceived threats
can have a large impact on our behaviors whether we want to admit it or not.
All in all, I enjoyed
this book and found it insightful to say the least. As mentioned in the intro,
I have had a couple of these thoughts to myself however I did not know the
technical terms that Tali Sharot is able to specialize in as a cognitive
neuroscientist. What I enjoyed the most from this book was the plethora of
examples and evidence provided for each concept introduced in the book. There were
many more I did not mention in the chapters I talked about, although they are just
as important as the ones I highlighted. This book was able to provide
educational information in an easily digestible way. I may not agree with all
of Tali Sharot’s priors or viewpoints presented in the book, however I believe
it was worth the read and is valid considering it is coming from an actual
professional in the field of cognitive neuroscience. If you read this book and actually absorb the information presented, it is possible you will notice your own biases and view your own brain differently.
