One might assume that training brains towards perfection is a worthy goal, but German neuroscientist Henning Beck's Scatterbrain promotes a different perspective. The book refutes received opinions about the brain's apparent inefficiencies, arguing that "these supposed weaknesses and imperfections are what make your brain so adaptable, dynamic, and creative."

Beck takes what look like intractable problems and finds the upside. Addressing forgetfulness, he asserts that unremembered information is not lost forever, just held in storage to be combined with other data and retrieved later. Regarding perspective around the passage of time, the book notes that intense or unusual experiences stand out in the memory, while routine ones are compressed.

As shown here, the human brain is always busy categorizing information, putting it into context, and making connections across time while filtering out what's unimportant in the short term. By taking occasional breaks and mixing up workloads, the book says, one can avoid distractions and become open to synthesizing information in new ways.

Chapters on mathematics, motivation, decision making, and creativity versus intelligence engage with a number of fields. Controversial subjects, including false memories and prejudice, come up for discussion, too. This is no dry reporting of facts, but a lively text full of exclamations, rhetorical questions, and conversational language. The book's colloquial English is occasionally shaky, as when describing the brain's behavior as "really annoying and dumb."

Relatable case studies share space with tests that can be used to assess short-term memory and attention, and everyday mysteries, such as why the mind goes blank under stress or how daydreaming can be fruitful, are also addressed. Scatterbrain is a fascinating work of popular neuroscience.

Neuroscientist Beck reveals how the brain's faults actually enhance its functionality in this delightful study. These integral flaws and errors "mask the hidden strengths of our brain," even as they create false memories, lead to math errors, and stymie decision-making. In a friendly and colloquial voice, with examples drawn from popular iconography and everyday life, Beck cites current research in neuropsychology to explain various mental phenomena—for example, why humans forget names and faces, how they learn from mistakes, and why they aren't adept at rote learning but understand the way the world works. A lively discussion about creativity shows why people are rarely innovative on demand but can generate new ideas that are neither planned nor regulated. Readers will come to appreciate how the brain's disorderly operating system is an advantage, and that being imperfect is what gives rise to new ideas, as Beck sums up when he pinpoints "the unique characteristic of human thought that it is not flawless and exact." Illuminating, and a joy to read, this offers, in comparison to other recent neuroscience titles, a refreshingly accessible and relatable take on the brain's inner workings that should appeal to both science buffs and casual readers.
