THE GAP

THE SCIENCE OF WHAT SEPARATES US FROM OTHER ANIMALS

A reader-friendly examination of the great gap that exists between human beings and the rest of the animal world and an explanation of how our minds came to be unique.

In his debut, Suddendorf (Psychology/Univ. of Queensland) first looks at what we have learned about the mental capacities of other primates, describing numerous experiments and both lean and rich interpretations of data. The author’s words for these differing interpretations are “killjoy” and “romantic,” respectively, and he takes a position midway between them. His descriptions of the many ingenious tests to assess the capabilities of various species and of human children make for fascinating reading. In language, intelligence, theory of mind, culture and morality, humans are set apart by the ability to imagine and reflect on different scenarios and by the desire to link their scenario-building minds together. Thus, while animals have communication, humans have an open-ended language; while they demonstrate problem solving, humans have abstract reasoning; while they have memory, humans have mental time travel; while they show evidence of traditions, humans have cumulative culture; and while they display empathy, humans have morality. As to how this gap came to exist, the author posits that Homo sapiens are just one branch of the various species of hominids that once existed and that our ancestors may have played a major role in eliminating their closest relatives on the family tree. “The reason the current gap between animal and human minds seems so large and so baffling, then,” writes the author, “may be because we have destroyed the missing links.” He warns that the gap will widen as humans drive the great apes into extinction, but in a surprisingly hopeful conclusion, he notes that humans are capable of choosing and creating a desirable future for ourselves and for our closest relatives.

A fine example of science made accessible for general readers, combining history, personal anecdotes, clear accounts of research and a broad picture of human evolution.

THINKING, FAST AND SLOW

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our...

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.

The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our minds.

MASTERY

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should...

Greene (The 33 Strategies of War, 2007, etc.) believes that genius can be learned if we pay attention and reject social conformity.

The author suggests that our emergence as a species with stereoscopic, frontal vision and sophisticated hand-eye coordination gave us an advantage over earlier humans and primates because it allowed us to contemplate a situation and ponder alternatives for action. This, along with the advantages conferred by mirror neurons, which allow us to intuit what others may be thinking, contributed to our ability to learn, pass on inventions to future generations and improve our problem-solving ability. Throughout most of human history, we were hunter-gatherers, and our brains are engineered accordingly. The author has a jaundiced view of our modern technological society, which, he writes, encourages quick, rash judgments. We fail to spend the time needed to develop thorough mastery of a subject. Greene writes that every human is “born unique,” with specific potential that we can develop if we listen to our inner voice. He offers many interesting but tendentious examples to illustrate his theory, including Einstein, Darwin, Mozart and Temple Grandin. In the case of Darwin, Greene ignores the formative intellectual influences that shaped his thought, including the discovery of geological evolution with which he was familiar before his famous voyage. The author uses Grandin's struggle to overcome autistic social handicaps as a model for the necessity for everyone to create a deceptive social mask.

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should beware of the author's quirky, sometimes misleading brush-stroke characterizations.
