Please note: This is a companion version & not the original book. Book Preview:

#1 The first set of skills is called neuropsychological humility. It involves knowledge of how your brain functions and is limited. The second category of skeptical gear is metacognition, which involves thinking about thinking. The third type of skeptical equipment is science, and the fourth category is core concepts that prepare you for your adventure.

#2 Scientific skepticism is an overall approach to knowledge that prefers beliefs and conclusions that are reliable and valid over ones that are comforting or convenient. It is a methodical approach to evaluating all empirical claims, and it values method over any particular conclusion.

#3 Being a skeptic means doubting, but it is not the same as philosophical skepticism, which is a position of permanent doubt. Scientific skepticism is a worldview that believes the world is knowable because it follows certain rules, or laws of nature.

#4 Skeptics are the first line of defense against incursions by pseudoscience. We seek to identify and elucidate the borders between legitimate science and pseudoscience, and to expose pseudoscience for what it is.

#1

The first set of skills is called neuropsychological humility. It involves knowledge of how your brain functions and is limited. The second category of skeptical gear is metacognition, which involves thinking about thinking. The third type of skeptical equipment is science, and the fourth category is core concepts that prepare you for your adventure.

#2

Scientific skepticism is an overall approach to knowledge that prefers beliefs and conclusions that are reliable and valid over ones that are comforting or convenient. It is a methodical approach to evaluating all empirical claims, and it values method over any particular conclusion.

#3

Being a skeptic means doubting, but it is not the same as philosophical skepticism, which is a position of permanent doubt. Scientific skepticism is a worldview that believes the world is knowable because it follows certain rules, or laws of nature.

#4

Skeptics are the first line of defense against incursions by pseudoscience. We seek to identify and elucidate the borders between legitimate science and pseudoscience, and to expose pseudoscience for what it is.

#5

The word skeptic in this book refers to an advocate for science and critical thinking. After reading the book, you may consider yourself a skeptic too.

#6

The invention of the airplane was widely anticipated in the early 1900s. Many people saw flying machines, and local newspapers reported how prominent citizens saw the ships and the pilot at the controls. But these were all hoaxes and mass delusions.

#7

Our memories are not accurate or passive recordings of the past. We do not have squishy camcorders in our skulls. Our memories serve more to support our beliefs than to inform them.

#8

There are two types of memory: declarative and procedural. Declarative memory is factual knowledge that can be recalled. Procedural memory is more automatic and involves learning how to do motor tasks such as throwing basketballs or writing in script.

#9

Memories are constantly being reconstructed and updated. We can fuse the details of different memories, and we can even combine two separate memories into one. We make shit up, and we invent details in order to emphasize the emotional significance of an event.

#10

We are all susceptible to the brain’s tendency to lie to us. We tend to shift memories from happening to other people to happening to ourselves, and we can be convinced that we committed a nonexistent crime after just three hours of interrogation by police.

#11

Memories can be distorted by suggestion. Merely suggesting a detail to someone while they are recalling a memory may cause them to incorporate that detail into their memory.

#12

The fact that we can’t recall most of the details from our flashbulb memories demonstrates just how unreliable they are. We tend to think that confidence in a memory and its accuracy are linked, but they aren’t.

#13

The 1980s saw the peak of an idea that was never based in science: the notion that people can suppress memories of traumatic events and those repressed memories can manifest as seemingly unconnected mental health issues, such as anxiety or eating disorders.

#14

The practice of recovered memory therapy is still ongoing today. However, the evidence does not justify the practice of recalling such memories. The potential for harm is more than sufficient grounds to suspend the practice pending further evidence.

#15

Optical illusions force us to confront the fact that what we think we see is not objective. Our brains process what we see, and that process can be fooled.

#16

Your real-time perceptions are not a passive recording of the outside world. Rather, they are an active construction of your brain. This means that there is an imperfect relationship between outside reality and the model of that reality crafted by your brain.

#17

Our brains process visual information, auditory information, sensation from our bodies, vestibular information about gravity orientation and acceleration, and feedback from our muscles to tell us how we’re moving. They favor continuity and internal consistency over accuracy.
