Don't Bother Me With Truth, Facts or Evidence.




If you've yet to read "The True Believer" by Eric Hoffer, you'd best get on it.

In a world ruled by True Believer ignorance and hutzpah, the more you know about this self-perpetuating phenomena, the better off you'll be.  Not happier or more content, rather less frustrated and ready to scream.

As to why people ignore facts, truth or science in what they believe, read on.

Why we stick to false beliefs: Feedback trumps hard evidence
New study finds that feedback rather than hard evidence makes us more confident that we're right

Ever wonder why flat earthers, birthers, climate change and Holocaust deniers stick to their beliefs in the face of overwhelming evidence to the contrary?  New findings from researchers at the University of California, Berkeley, suggest that feedback, rather than hard evidence, boosts people's sense of certainty when learning new things or trying to tell right from wrong.

Developmental psychologists have found that people's beliefs are more likely to be reinforced by the positive or negative reactions they receive in response to an opinion, task or interaction, than by logic, reasoning and scientific data.

Their findings, published in the online issue of the journal Open Mind, shed new light on how people handle information that challenges their worldview, and how certain learning habits can limit one's intellectual horizons.

"If you think you know a lot about something, even though you don't, you're less likely to be curious enough to explore the topic further, and will fail to learn how little you know," said study lead author Louis Marti, a Ph.D. student in psychology at UC Berkeley.

This cognitive dynamic can play out in all walks of actual and virtual life, including social media and cable-news echo chambers, and may explain why some people are easily duped by charlatans.

"If you use a crazy theory to make a correct prediction a couple of times, you can get stuck in that belief and may not be as interested in gathering more information," said study senior author Celeste Kidd, an assistant professor of psychology at UC Berkeley.

Specifically, the study examined what influences people's certainty while learning. It found that study participants' confidence was based on their most recent performance rather than long-term cumulative results. The experiments were conducted at the University of Rochester.

For the study, more than 500 adults, recruited online through Amazon's Mechanical Turk crowdsourcing platform, looked at different combinations of colored shapes on their computer screens. They were asked to identify which colored shapes qualified as a "Daxxy," a make-believe object invented by the researchers for the purpose of the experiment.

With no clues about the defining characteristics of a Daxxy, study participants had to guess blindly which items constituted a Daxxy as they viewed 24 different colored shapes and received feedback on whether they had guessed right or wrong. After each guess, they reported on whether or not they were certain of their answer.

The final results showed that participants consistently based their certainty on whether they had correctly identified a Daxxy during the last four or five guesses instead of all the information they had gathered throughout.

"What we found interesting is that they could get the first 19 guesses in a row wrong, but if they got the last five right, they felt very confident," Marti said. "It's not that they weren't paying attention, they were learning what a Daxxy was, but they weren't using most of what they learned to inform their certainty."

An ideal learner's certainty would be based on the observations amassed over time as well as the feedback, Marti said.

"If your goal is to arrive at the truth, the strategy of using your most recent feedback, rather than all of the data you've accumulated, is not a great tactic," he said.

How the lives of Georgian gaolbirds and highwaymen shaped modern Britain

Writing historical fiction requires solid research of available materials and databases.  The key word here is available.   So news of a new publicly accessible database that allows an author to research a very interesting past era is priceless almost beyond words.   I expect some exciting fiction to come out of this announcement. Here's the story, with a link to the source in the attribution. *  *  *  *  * London Lives, a landmark project led by Professor Bob Shoemaker from the University of Sheffield and Professor Tim Hitchcock from the University of Sussex, has uncovered a mass of extraordinary new evidence which reveals how the lives of thousands of 18th-century poor and criminal Londoners helped shape modern Britain. Based on evidence made available in a publicly available database, the study sheds new light on the everyday lives of thieves, prostitutes, vagrants, highwaymen, con-men, paupers and jailbirds, revealing how their daily fight for survival led to t

An unexpected way to recover from a breakup

Image
Breaking up is truly hard to do. And recovery from a breakup can be even harder. Your friends may counsel you to put the whole thing out of your mind. But new research suggests that repeatedly reflecting on a break-up -- even through participation in a research study -- actually speeds emotional recovery. "Breakups are ubiquitous -- most adults have experienced at least one in their life -- and are typically very distressing," says Grace Larson of Northwestern University. After studying divorce and breakups for years using longitudinal, multi-method designs, Larson and her then-adviser David Sbarra of the University of Arizona wanted to study whether these research techniques on their own were affecting participants. One concern they had was that the studies could be harming participants, Larson says. "At first glance, it might seem like repeatedly reminding participants that they had just broken up -- and asking them to describe the breakup over and over --

Greek Bronze Age ended 100 years earlier than thought

Writing historical fiction set in the Greek Bronze Age?  Or simply enjoy reading this genre'?  Here's a study you may find interesting. C onventional estimates for the collapse of the Aegean civilization may be incorrect by up to a century, according to new radiocarbon analyses. While historical chronologies traditionally place the end of the Greek Bronze Age at around 1025 BCE, this latest research suggests a date 70 to 100 years earlier. www.weather-forecast.com Archaeologists from the University of Birmingham selected 60 samples of animal bones, plant remains and building timbers, excavated at Assiros in northern Greece, to be radiocarbon dated and correlated with 95.4% accuracy using Bayesian statistical methodology at the University of Oxford and the Akademie der Wissenschaften Heidelberg, Germany. Researcher Dr Ken Wardle says, 'These new results tell a story that is totall

Mood Instability and Your Characters

Image
You're putting together a character who's mood simply bounces all over the place, happy one moment, in a fit of rage the next.  Researchers at King's College London note that this sort of mood instability is part of a number of mental health disorders.  So how do you structure the personality and behavior of a character like this?  Below is the King's College report, along with a brief description from mentalhealth.com, of typical behavior, sometimes in the extreme, of a person who is very emotionally unstable.  This is offered strictly as a guide for crafting character in fiction - and NOT for the amateur diagnosis of the state of someone's mental health.  That is always best left to trained professionals. Another note about emotionally unstable behavior:  as any parent will tell you, this is how adolescents and teen-agers often behave.  It's a normal part of growing up - but it is a matter of degree .  In the extreme, however, this behavior can be diag

Remember faces but not names? You got it wrong.

New research has revealed we are actually better at remembering names than faces The cringe-worthy experience of not being able to remember an acquaintance's name leads many of us to believe we are terrible with names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces. With the Christmas party season fast approaching, there will be plenty of opportunity to re-live the familiar, and excruciatingly-awkward, social situation of not being able to remember an acquaintance's name. This cringe-worthy experience leads many of us to believe we are terrible at remembering names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces.
