General Overview: “How We Know What Isn’t So”
This book
focuses on the common errors people make when trying to comprehend the world
around them and ways to avoid making those errors. The book spent time explaining the realms of pseudo scientific beliefs and testing to disprove those believes. The book forces you to question yourself and
your assumptions about the world around you.
The Author, Thomas Gilovich uses real research
data and logical opinions to support his claims throughout the book. He encourages the reader to think outside of
the box.
The book is divided into four main sections. In part one of the book, Gilovich’s stressed that people will ultimately believe what they
want to believe. Humans want to find
order/ patterns in the world around them even when they do not exist. Most people find randomness unsettling and
difficult to comprehend. In part, two of
the book the author explains how people only see what they want to see. People will filter what they hear
according to their own biases/needs and that wishful thinking can distort
reality. In part, three of the book he
focuses on the use of ineffective health practices and the idea of holistic medicine. He sets up the cases in this section in a
very readable way and then discusses the possible consequences of the
misbelieves. In part, four of the book
he offers strategies to fight our tendencies to reason incorrectly.
Favorite
Part / Class Connection
My favorite part of the book was the section on ineffective
and alternative health practices. This
part was the most interesting to me because it brought up information that was
also introduced within our class. The
book discusses how people tend to believe that a certain treatment will work
even though medical science has evidence to support that is does not benefit
the patient. In some examples, it even harmed the patient!
Creative
Connection
I was struggling with the creative part of the report
until my daughter called me for some advice over my new grandson. Tommy (the cutest baby ever!) was running a
fever and was up screaming at night. She
did take him to the doctors and they informed her that it was a virus and it
had to run its course. Then it hit me… let’s ask people what they do to help a
sick child at night. My daughter created
a post on Facebook asking people for
advice on how to help Tommy. I was amazed at all of the different answers. Some of the most common answers from Facebook
included ideas that have no scientific evidence behind them but the mothers
were adamant that they work. The most
common answers on face book included putting Vicks vapor rub on the baby’s feet
and then covering them with socks and giving the child large doses of vitamin
C. Unfortunately , despite the near universal belief that these methods will work, there is little
to no evidence supporting the usefulness of most home remedies. I think this is a great example of people
believing what they want despite scientific data that shows the opposite.
Extension
I truly enjoyed
reading this book. It made me question
my own thinking and how I perceive and process information. It caused me to think about my own common misconceptions and believes. I believed several things to be
common knowledge for most of my life only to find out that it is not backed by
data. I always thought that your heart
stopped when you sneezed, that too much sugar would make kids hyperactive and
that chicken soup would help the common cold.
Most of the scientific data does not back up this common knowledge
believes.
Extra
Information
I found a great video from one of my favorite
celebrity scientists, Bill Nye, about pseudoscience. The video is slightly dated but I do think it
makes some very relevant points.
Feel free to watch and I hope you enjoy it J
