What is the focusing illusion? How does it affect your memory of an event? The focusing illusion is a cognitive bias that happens when you focus too much on one aspect of an experience. This keeps you from holding an accurate memory of the experience as a whole and leads to bad predictions about future experiences. We’ll cover what the focusing illusion is, how it affects what we predict will make us happy, and how to counter it.
What’s an indifference curve? How does it explain how much I value my belongings? Where is it inaccurate? An indifference curve is a graph that demonstrates goods are quantities that a person sees as equal in value. Indifference curves don’t always accurately describe reality–for instance, they can’t explain why we tend to overvalue our belongings. We’ll cover the indifference curve definition and the properties of indifference curves.
What is the law of small numbers? How does ignoring it lead to biased decision-making? The law of small numbers is the bias of making generalizations from a small sample size. In truth, the smaller your sample size, the more likely you are to have extreme results. If you’re not aware of this principle, when you have small sample sizes, you may be misled by outliers. We’ll cover two examples of the law of small numbers in action and how to use your awareness of it to make better decisions.
What is the meaning of “priming” in psychology? How does priming work? When is it useful? Why is it controversial? Priming is a technique based on the theory that when an idea is triggered, its associations can cause you to behave in a meaningfully different way without your consciously realizing it. The concept of priming takes the idea of association beyond mere thought, to the functional level. We’ll cover what priming is, how it’s used, and why it’s controversial.
In the future, intelligent design could replace natural selection through biological engineering. What is biological engineering? Biological engineering is when scientists intervene with an organism’s biology to change its physical, behavioral, or emotional characteristics. For these reasons, biological engineering projects are often controversial. We’ll cover examples of biological engineering that’s already happing and biological engineering plans for the future. We’ll also look at other ways intelligent design could replace natural selection.
What does the future of the human race hold? Will we remain the same race, Homo sapiens, that we are now? In the future of the human race, intelligent design could replace natural selection in one of two ways (or a combination of the two): cyborg engineering and biological engineering. We’ll cover what these are and what new questions they’ll introduce to the future human race.
We think of our own species as the only humans, distinguished from and superior to every other species on earth. But when we, Homo sapiens, arrived on the scene 2.5 million years ago, we weren’t anything special. We existed in the middle of the food chain, as often prey as we were predators, and we weren’t even the only humans. Why did Homo Sapiens survive while other human species disappeared? Homo Sapiens survived due to their advanced linguistic abilities and communication skills. The way Homo Sapiens used language affected their ability to hunt, trade, and dominate the animal kingdom. We’ll
What is narrow framing? Does it help or hinder our decision-making process? Narrow framing is when you focus on the details at the expense of the big picture. Narrow framing can hurt your decision-making skills because it keeps you from seeing your choices in context. We’ll cover what narrow framing is, how it differs from broad framing, and how to counter narrow framing in your everyday life.
What does “regression toward the mean” mean in psychology? How does it apply to everyday life? Regression toward the mean refers to the principle that, over repeated sampling periods, outliers tend to revert to the mean. High performers show disappointing results when they fail to continue delivering; strugglers show sudden improvement. We’ll cover what it means to regress toward the mean in psychology, 7 examples of regression toward the mean, and how to counter biases related to this phenomenon.
What is associative thinking? What is its function, and how might it lead to bias? Associative thinking is fast, subconscious thinking that associates one concept with another. The ideas can involve memories, emotions, and physical sensations. We’ll cover how associative thinking works and how you use it in everyday life.
