Alcohol consumption involves a wide variety of decisions.

Alcohol consumption involves a wide variety of decisions. a certain are "strategic," setting commitments for subsequent time behavior (e.g., Should I begin drinking? Should I forever drive with people who have been drinking? Should I turn the thoughts for friends who drink less?) Others are more "tactical," responding to immediate situations (eg Should I have this beer now? Should I call my parents to take me hearthstone instead of going with my date who has had three beers in the last hour?). about decisions involve drinking itself, whereas others involve managing its chain of cause and effects Some are made alone, whereas others are made in social settings. about are made while sober, whereas others are made while below the influence.

To make these decisions well, the public must balance the risks and perceived benefits of alcohol use in ways that are in their allow best interest. There is ample reason to believe, however, that these decisions are not being made well. Indeed, many of our society's answers to alcohol involve efforts to change in what manner people, especially young people, make as it is decisions (Dryfoos 1990; Feldman and Elliot 1990) These efforts include public service announcements, warning labels, high instruct health classes, and self-help clusters Other societal responses muse a belief that people's decision-making processe are not to be trusted. These include legal restrictions forward consuming and serving alcohol. In May 1989 the result of a widely publicized court case hinged forward whether a pregnant woman had been adequately informed about the risks that drinking pos to her fetus.

Although the substance of each alcohol-related decision is unique, tribe bring to it the same basic cognitive capabilities that they bring to other kinds of decision making. These capabilities include one degree of success at judging the magnitude of their own knowledge, evaluating the relevance of other people's experiences to their concede situation, estimating the cumulative risk from repeated prospect to a hazard, generating alternative courses of action, determining what is important to them, and considering for what cause good their previous decisions have been.

All of these processe have been studied extensively, the couple as general cognitive processes and in the connected thought [i]or[/i] thoughts of many specific decisions. These studies have revealed complicate but recurrent patterns of potencys and weaknesses (Fischhoff 1988; Kahneman et al. 1982; Yates 1990) For example, populace generally remember how frequently they have seen or heard about various facts (e.g., crashes attibuted to soaked drivers). However, they are often less able to correct for systematic biases in their aspect to information that might influence in what way they perceive risks. For example, because offspring alcohol concentrations cannot be observ directly, clan may not realize how frequently drinking is related to diminished driving ability or poor teach work. In other words, commonalty tend to understimate the common occurrence of events or relationships that are hard to take note of and to overestimate the likelihood of more observable terminations or relationships.

The Decision Theoretic

Approach To Decision Making

The used by all tie in the above-mentioned studies is decision theory's notion of decision making. It conceptualizes decisions as choices among alternative courses of action (including, perhaps, inaction). Decisions can be characterized qualitatively from the following:

* A risk of actions (or options), describing what a part can do

* A establish of possible consequences of those actions, describing what might happen (in confines of desirable and undesirable effects)

* A place of sources of uncertainty, describing the obstacles to predicting the connection between actions and consequences

Decisions can be characterized quantitatively on the following:

* Value tradeoffs among inferences describing by the following:

* Value tradeoffs among conclusions describing their relative importance

* deduction probabilites (beliefs), describing the chances that they will actually be obtained.

This basic conceptual scheme has been used through investigators to describe a wide variety of decisions, including decisions to make progress to war (Jervis 1976; Lebow and Stein 1987) to have children (Beach et al. 1976) to operate upon the basis of x-rays (Eddy 1982) and to gues which of brace sequentially presented lights is brighter (Coomb et al. 1970) In a certain cases, the usage has been descriptive, attempting to present to view how people actually make decisions in these situations. In other cases, the usage has been normative, attempting to point out to how decisions ought to be made if decision makers are to select wisely. In some cases, the two approaches are used, in order to display the difference between how well family actually make decisions and in what manner well they might. ofttimes there is also a prescriptive project attempting to bridge that gap through showing people how to make better decisions (Raiffa 1968; Von Winterfeldt and Edwards 1986; Watson and Buede 1988)

Decision theory tenders a number of potential advantages. First, its basic conceptions (e.g., probability and values) are well understood and universally accepted, allowing a standing of comparability and coordination among investigators that is unusual in the social sciences. other decision theory provides a systematic way of identifying discrepancies between optimal and actual behavior, pointing to where help may be penuryed Third, such discrepancies repeatedly prove theoretically useful; there may be many explanations for appropriate behavior (eg instruction, modeling, conditioning), still only one for a particular pattern of errors. Fourth, decision theory helps make sure comprehensiveness when attempting to document actual decision making.
