Eyewitnesses and emotion: A reminder to engage critical thinking

12/4/2014

 
By Sharon Hill

Faye Flam, science writer and presenter at TAM2013, published a piece this past week on Forbes that resonated with skeptical audiences.  Or at least it should have. 

She was writing about how the Ferguson shooting of Michael Brown was fraught with problematic eyewitness testimony that was inconsistent, made up, or factually wrong.  The unreliability of such testimony and the malleability of memory is a core concept in evaluating evidence, especially in cases of unusual events or crime situations. 

The piece, What Science Says About The Ferguson Case: Memory Can Be Hacked, also referenced long-time JREF friend and TAM presenter Elizabeth Loftus.  Dr. Loftus’ book Eyewitness Testimony should be required reading, in my opinion, for any investigator or researcher into extraordinary claims. Thanks to Dr. Loftus’ (and others') work, we now are in no doubt that memory recall and eyewitness testimony can be perilous. It can send people to jail, destroy families, and… it can intensify civil unrest and national strife, as it has these past few weeks centered upon a troubled neighborhood in Missouri.

Flam’s article in Forbes should have resonated with a skeptical audience for another reason - the problem of letting emotion overwhelm facts.  When it comes to hot-button, impassioned issues, everyone will interpret “facts” in terms of their own world view. This will differ between us creating dissonance. But we, as the bystanders and over-the-fence-peekers into the Ferguson Grand Jury proceedings, did not hear the complete case as they did. Unless you were on the jury (or read the voluminous testimony carefully) you did not know the facts used in the decision and should not be making judgments as if you did [1].

I recommend a Critical Thinking (CT) scan

This is the first in a series of essays examining the importance of applying active thought processes, some deeper thinking, to issues we face everyday. It is written for the parent, teacher or mentor to enforce the idea that learning how to think through situations and claims is a valuable skill for a more fulfilling life. Passively consuming information or swallowing whole what we are told can lead to errors and poor judgments that can cost us dearly.

Computed tomography (CT) is a type of imaging used to aid medical diagnoses. Special x-ray equipment is used to make cross-sectional pictures of your body. Doctors use CT scanning procedures to look for broken bones, tumors, blood clots, signs of heart disease and other problems that are not obvious on the surface but can seriously affect a person’s health. [1] The analogy of a body CT scan is appropriate when examining claims and information we get everyday in the media and our social spheres.

It’s easy to take a quick look at a conclusion, a news story, a status report, a recommendation, etc. and assume it’s on the up and up, that it is OK to accept at face value, and act accordingly without further contemplation. But some issues deserve a closer look, especially decisions that might affect your health, finances or the well-being of you and your family. 

What if there is an important issue that you are asked to decide or vote on? Does it make sense to vote along your political party lines or choose based on what your neighbors and friends say is right? It make more sense to investigate the issue for yourself to decide what is best for your greater good.

So, indulge me in this analogy of a CT scan - critical thinking scan – to discuss why it’s important to take the extra time and effort to examine claims more deeply to see what could be concealed inside.

    SWIFT is named after Jonathan Swift, the author of Gulliver's Travels. In the book, Gulliver encounters among other things a floating island inhabited by spaced-out scientists and philosophers who hardly deal with reality. Swift was among the first to launch well-designed critiques against the flummery - political, philosophical, and scientific - of his time, a tradition that we hope to maintain at The James Randi Foundation.
