Humans are hardwired to dismiss facts that don’t fit their worldview

“Human cognition is inseparable from the unconscious emotional responses that go with it.”

In theory, resolving factual disputes should be relatively easy: Just present the evidence of a strong expert consensus. This approach succeeds most of the time when the issue is, say, the atomic weight of hydrogen.

But things don’t work that way when the scientific consensus presents a picture that threatens someone’s ideological worldview. In practice, it turns out that one’s political, religious, or ethnic identity quite effectively predicts one’s willingness to accept expertise on any given politicized issue.

An algorithm that can spot cause and effect could supercharge medical AI

How do we make better use of this piecemeal information? Computers are great at spotting patterns—but that’s just correlation. In the last few years, computer scientists have invented a handful of algorithms that can identify causal relations within single data sets. But focusing on single data sets is like looking through keyholes. What’s needed is a way to take in the whole view.

Why Are Deepfakes So Effective? It’s because we often want them to be true

Developing deep fake detection technology is important, but it’s only part of the solution. It is the human factor—weaknesses in our human psychology—not their technical sophistication that make deep fakes so effective. New research hints at how foundational the problem is.

The biggest threat of deepfakes isn’t the deepfakes themselves

“Deepfakes do pose a risk to politics in terms of fake media appearing to be real, but right now the more tangible threat is how the idea of deepfakes can be invoked to make the real appear fake,” says Henry Ajder, one of the authors of the report. “The hype and rather sensational coverage speculating on deepfakes’ political impact has overshadowed the real cases where deepfakes have had an impact.”

Why people believe the Earth is flat and we should listen to anti-vaxxers

Science communication has lost its sense of empathy and misunderstands how fear can alter a person’s belief system.

When we feel so fundamentally disenfranchised, it’s comforting to concoct a fictional universe that systemically denies you the right cards. It gives you something to fight against and makes you self-deterministic.

It provides an “us and them” narrative that allows you to conceive of yourself as a little David raging against a rather haughty, intellectual establishment Goliath.

Mental Models: The Best Way to Make Intelligent Decisions (109 Models Explained)

Screen Shot 2019-06-01 at 11.50.02 PM.pngMental models are how we understand the world. Not only do they shape what we think and how we understand but they shape the connections and opportunities that we see. Mental models are how we simplify complexity, why we consider some things more relevant than others, and how we reason.

A mental model is simply a representation of how something works. We cannot keep all of the details of the world in our brains, so we use models to simplify the complex into understandable and organizable chunks.
