Book Notes Chapter 7-Group Discussion: Defective Group Decision Making  and Problem Solving Confirmation Bias-  our strong tendency to seek information that confirms our beliefs  and attitudes and to ignore information that contradicts our currently held beliefs and  attitudes.  We listen to those who will likely tell us what confirms our current beliefs and  more rarely listen to those who might challenge those beliefs.   It is a prime example of a mindset that can produce defective decision making and  problem solving.  In many research, it is very common.   The competent communicator combats the problem of confirmation bias by taking the  following steps: 1. seek disconfirming information and evidence.  Since most group members will be  predisposed to seek confirming evidence, someone will have to perform an error- correction function for the group. If, after a concerted effort, you find little  disconfirming evidence of note, then your decision or solution has an excellent  chance of turning out well.  2. vigorously present disconfirming evidence to the group.  Be persistent. Members  will usually ignore information that disconfirms a strongly held belief unless you  assert yourself.  Sometimes messengers with bad news are received as heroes  when they prevent the group from making an embarrassing error.  3. play devils advocate. Develop a habit of asking yourself and others the question  “so what’s another side of the issue?” 4. gather allies to help challenge confirmation bias. Women and ethnic minorities  especially profit from developing support with those members of a group who are  respected and open minded.   Rationalization of disconfirmation-  group members invent superficial, even glib  alternative explanations for information that contradicts a belief. The perpetuation of  unwarranted beliefs is the result of confirmation bias and its ally, rationalization of  disconfirmation.   Information Overload/Under load Information overload occurs when the rate of information flow into a system and/or the  complexity of that information exceed the systems processing capacity.  IO is not  inconsequential.  There are four main consequences of IO relevant to group decision  making and problem solving.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
