  • Fast thinking - Unconsious, emotional, instictive.

    • Results in snap judgements and, sometimes, prejudices.
  • Slow thinking - Considered as actual thoughts

    • Conscious; Deliverative, and mostly rational.

The process was mental work: deliberate, effortful, and orderly—a prototype of slow thinking.

Two Systems

  • System 1 (S1) operates automatically and quickly, with little or no effort and no sense of voluntary control.

  • System 2 (S2) allocates attention to the effortful mental activities that demand it, including complex computations. The operations of System 2 are often associated with the subjective experience of agency, choice, and concentration.

System 1 effortlessly creates impressions and feelings that are the main sources of explicit beliefs and deliberate choices of System 2.

  • S1 generates suprisingly complex patterns of ideas; S2 construct thoughts in an orderly series of steps.

Plot Synopsis

  • S1 runs automatically and S2 is normally in a comfortable low-effor mode.
