Choice Definition and 693 Threads

A choice is the range of different things from which you can choose. The arrival at a choice may incorporate motivators and models. For example, a traveler might choose a route for a journey based on the preference of arriving at a given destination at a specified time. The preferred (and therefore chosen) route can then account for information such as the length of each of the possible routes, the amount of fuel in the vehicle, traffic conditions, etc.
Simple choices might include what to eat for dinner or what to wear on a Saturday morning – choices that have relatively low-impact on the chooser's life overall. More complex choices might involve (for example) what candidate to vote for in an election, what profession to pursue, a life partner, etc. – choices based on multiple influences and having larger ramifications.
Freedom of choice is generally cherished, whereas a severely limited or artificially restricted choice can lead to discomfort with choosing, and possibly an unsatisfactory outcome. In contrast, a choice with excessively numerous options may lead to confusion, reduced satisfaction, regret of the alternatives not taken, and indifference in an unstructured existence;
and the illusion that choosing an object or a course, necessarily leads to the control of that object or course, can cause psychological problems.
