The Left Brain Interpreter and Sense-Making

What is the “left brain interpreter”? How does the brain assimilate new information? The left brain interpreter is a neurophysiological concept that refers to the brain’s process of making sense of new information by relating it to existing knowledge. Although the concept was based on the studies of split-brain patients—patients who had their corpus callosum severed—it applies to neurotypical populations at large. Keep reading to learn about the left brain interpreter and its role in sense-making.

Implicit Association Test: The Psychology of Bias

What is the Implicit Association Test (IAT)? How does the IAT measure bias? In psychology, the Implicit Association Test (IAT) is an assessment designed to gauge mental representations that are outside conscious control.

Blink: The Power of Thinking Without Thinking

What is Malcolm Gladwell’s Blink about? What can Gladwell teach you about decision-making? In his book Blink: The Power of Thinking Without Thinking (2005), Malcolm Gladwell argues that snap decisions made on the fly could be as good as decisions made through deliberate, rational thinking. Blink delves into how and why we make the gut decisions we do, when it’s unsafe to trust our guts, and what we can do to make all our snap judgments smarter, less biased, and more efficient. Here’s an overview of Blink by Malcolm Gladwell.

Blink: The Psychology of Snap Judgments

How accurate are snap judgments? What are the dangers inherent in making snap judgments—sizing up a situation based on superficial information, without much conscious deliberation? Snap judgments can go wrong for a few reasons: First, we can be overly superficial when making a judgment. Second, we can fail to recognize when our conscious and unconscious attitudes don’t match, which leads us to make decisions that are inconsistent with our conscious beliefs. And third, we’re far more susceptible to the effects of priming than we think. Learn about the psychology of snap judgments and how they can go wrong.

The Power of Snap Decisions: Decide, Don’t Think

How do we make snap decisions? In what circumstance is it a good idea to make a snap decision, trusting your gut? Snap decisions are made on the fly—unconsciously, without rational deliberation. But that’s not necessarily a bad thing. According to Malcolm Gladwell, the author of Blink, in some circumstances, it’s better to decide on the fly than to deliberate on how to proceed. Keep reading to learn about the power of snap decision-making, why some snap decisions are better than others, and how to make better snap decisions.

Rationalization: The Psychology of Denial

Why is irrationality so uncomfortable? Can knowledge that is not backed by a rational explanation ever be true? Why do we feel such a strong urge to rationalize our decisions and behaviors? Knowledge without a rational explanation is a double-edged sword. This type of knowledge can be the truest, deepest kind, but it can also harbor biases. Because most of us don’t feel comfortable if we don’t know exactly what made us arrive at a particular judgment or decision, we tend to rationalize. But instead of helping us to uncover the truth, rationalizing often takes us further away from it.
