Every decision is made within a decision environment, which is defined as the collection of information, alternatives, values. Many decision makers have a(n)  50 to seek more information than required to make a good decision. When too much information is sought and obtained, one or more of several   51 can arise.
﹡ A   52  in the decision occurs because of the time required to obtain and process the extra information.
  53  overload will occur. In this state, so much information is available that decision-making ability actually   54  because the information in its entirety can no longer be managed or assessed  55 . A major problem caused by information overload is  56 . When too much information is taken into memory, especially in a short period of time, some of the information (often that received early on) will be pushed out.
﹡Selective use of the information will occur.  57   , the decision maker will choose from among all the information available only those facts which support a preconceived(预先构想的) solution or position.
﹡Mental fatigue occurs, which  58  slower work or poor quality work.
  59   fatigue occurs, where the decision maker tires of making decisions. Often the result is fast, careless decisions or no decisions are made at all.
The quantity of information that can be processed by the human mind is limited. Unless information is  60 selected, processing will be biased toward the first part of the information received. After that, the mind tires and begins to  61 subsequent information or forget earlier information.
A common   62 about decision making is that decisions are made in isolation from each other: you gather information, explore alternatives, and  63 , without regard to anything that has gone before. The fact is, decisions are made in a context of other decisions.
We might say, then every decision  64  from previous decisions: enables many future decisions, and assists other future decisions.
