Deciding Advantageously Before Knowing the Advantageous Strategy

Bechara, Antoine, Damasio, Hanna, Tranel, Daniel, Damasio, Antonio R.·1997·Science

Abstract

Deciding advantageously in a complex situation is thought to require overt reasoning on declarative knowledge, namely, on facts pertaining to premises, options for action, and outcomes of actions that embody the pertinent previous experience. An alternative possibility was investigated: that overt reasoning is preceded by a nonconscious biasing step that uses neural systems other than those that support declarative knowledge. Normal participants and patients with prefrontal damage and decision-making defects performed a gambling task in which behavioral, psychophysiological, and self-account measures were obtained in parallel. Normals began to choose advantageously before they realized which strategy worked best, whereas prefrontal patients continued to choose disadvantageously even after they knew the correct strategy. Moreover, normals began to generate anticipatory skin conductance responses (SCRs) whenever they pondered a choice that turned out to be risky, before they knew explicitly that it was a risky choice, whereas patients never developed anticipatory SCRs, although some eventually realized which choices were risky. The results suggest that, in normal individuals, nonconscious biases guide behavior before conscious knowledge does. Without the help of such biases, overt knowledge may be insufficient to ensure advantageous behavior.

  1. We envision these biases to act as markers or qualifiers in the manner suggested by A. Damasio [in (5) chap. 8] and by A. R. Damasio D. Tranel and H. Damasio [in Frontal Lobe Function and Dysfunction H. S. Levin H. M. Eisenberg A. L. Benton Eds. (Oxford Univ. Press New York 1991) pp. 217]. See also P. R. Montague P. Dayan C. Person T. J. Sejnowski Nature 377 725 (1995); This action might occur both at the cortical level and in subcortical structures such as basal ganglia.
  2. The Nervous System F. Plum Ed. (American Physiological Society Bethesda MD 1987) vol. 5 pp. 373-401] and selective attention [M. I. Posner and S. Dehaene Trends Neurosci. 17 75 (1994). In other words we propose an addition to mechanisms already recognized as necessary for proper reasoning rather than an alternative to those mechanisms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
