For an integrated discussion of the mind, its evolution, and its natural abilities, there are few better sources than Steven Pinker’s The Blank Slate and How the Mind Works.

  Chapter One: The Scientific Method of the Mind

  For the history of Sherlock Holmes and the background of the Conan Doyle stories and Sir Arthur Conan Doyle’s life, I’ve drawn heavily on several sources: Leslie Klinger’s The New Annotated Sherlock Holmes; Andrew Lycett’s The Man Who Created Sherlock Holmes; and John Lellenerg, Daniel Stashower, and Charles Foley’s Arthur Conan Doyle: A Life in Letters. While the latter two form a compendium of information on Conan Doyle’s life, the former is the single best source on the background for and various interpretations of the Holmes canon.

  For a taste of early psychology, I recommend William James’s classic text, The Principles of Psychology. For a discussion of the scientific method and its history, Thomas Kuhn’s The Structure of Scientific Revolutions. Much of the discussion of motivation, learning, and expertise draws on the research of Angela Duckworth, Ellen Winner (author of Gifted Children: Myths and Realities), and K. Anders Ericsson (author of The Road to Excellence). The chapter also owes a debt to the work of Daniel Gilbert.

  Chapter Two: The Brain Attic

  One of the best existing summaries of the research on memory is Eric Kandel’s In Search of Memory. Also excellent is Daniel Schacter’s The Seven Sins of Memory.

  John Bargh continues to be the leading authority on priming and its effects on behavior. The chapter also draws inspiration from the work of Solomon Asch and Alexander Todorov and the joint research of Norbert Schwarz and Gerald Clore. A compilation of research on the IAT is available via the lab of Mahzarin Banaji.

  Chapter Three: Stocking the Brain Attic

  The seminal work on the brain’s default network, resting state, and intrinsic natural activity and attentional disposition was conducted by Marcus Raichle. For a discussion of attention, inattentional blindness, and how our senses can lead us astray, I recommend Christopher Chabris and Daniel Simon’s The Invisible Gorilla. For an in-depth look at the brain’s inbuilt cognitive biases, Daniel Kahneman’s Thinking, Fast and Slow. The correctional model of observation is taken from the work of Daniel Gilbert.

  Chapter Four: Exploring the Brain Attic

  For an overview of the nature of creativity, imagination, and insight, I recommend the work of Mihaly Csikszentmihalyi, including his books Creativity: Flow and the Psychology of Discovery and Invention and Flow: The Psychology of Optimal Experience. The discussion of distance and its role in the creative process was influenced by the work of Yaacov Trope and Ethan Kross. The chapter as a whole owes a debt to the writings of Richard Feynman and Albert Einstein.

  Chapter Five: Navigating the Brain Attic

  My understanding of the disconnect between objective reality and subjective experience and interpretation was profoundly influenced by the work of Richard Nisbett and Timothy Wilson, including their groundbreaking 1977 paper, “Telling More Than We Can Know.” An excellent summary of their work can be found in Wilson’s book, Strangers to Ourselves, and a new perspective is offered by David Eagleman’s Incognito: The Secret Lives of the Brain.

  The work on split-brain patients was pioneered by Roger Sperry and Michael Gazzaniga. For more on its implications, I recommend Gazzaniga’s Who’s in Charge?: Free Will and the Science of the Brain.

  For a discussion of how biases can affect our deduction, I point you once more to Daniel Kahneman’s Thinking, Fast and Slow. Elizabeth Loftus and Katherine Ketcham’s Witness for the Defense is an excellent starting point for learning more about the difficulty of objective perception and subsequent recall and deduction.

  Chapter Six: Maintaining the Brain Attic

  For a discussion of learning in the brain, I once more refer you to Daniel Schacter’s work, including his book Searching for Memory. Charles Duhigg’s The Power of Habit offers a detailed overview of habit formation, habit change, and why it is so easy to get stuck in old ways. For more on the emergence of overconfidence, I suggest Joseph Hallinan’s Why We Make Mistakes and Carol Tavris’s Mistakes Were Made (But Not by Me). Much of the work on proneness to overconfidence and illusions of control was pioneered by Ellen Langer (see “Prelude”).

  Chapter Seven: The Dynamic Attic

  This chapter is an overview of the entire book, and while a number of studies went into its writing, there is no specific further reading.

  Chapter Eight: We’re Only Human

  For more on Conan Doyle, Spiritualism, and the Cottingley Fairies, I refer you once more to the sources on the author’s life listed in chapter one. For those interested in the history of Spiritualism, I recommend William James’s The Will to Believe and Other Essays in Popular Philosophy.

  Jonathan Haidt’s The Righteous Mind provides a discussion of the difficulty of challenging our own beliefs.

  Postlude

  Carol Dweck’s work on the importance of mindset is summarized in her book Mindset. On a consideration of the importance of motivation, see Daniel Pink’s Drive.
