how to limit bias?

I had this thought that in order to make a robust decision > you have to eliminate/limit bias. What is the easiest way to do that? I would suggest that i.e. during team decision making it should be each individual to acknowledge one's bias and limit it (some help from other members is allowed, though).

In one article, the researchers listed 76 biases and groupped them in 5 categories. How on earth would one control that amount of biases?????? Try to think of them before saying each sentence ;)

What is more, one of the biases was cultural bias. Now this is something I've come across, it's quite obvious in some cases, however it is obvious for listeners, not for the person who is saying.... The battle with bias seems to be lost right at the start...

    You know, I’m grappling with this issue at the moment. Judgement biases often occur quickly and subconsciously within an individuals mind, aside from being consciously aware of a few biases you may be subject to (certainly not the entire 76 you came across!) i am not sure how else they may be prevented

    I agree with you, the battle with bias is lost right from the start because even the process of choosing a decision technique to make a robust decision is subject to bias. I remember in our final seminar for the RDM class, Jeff made a comment that the AHP was one of the techniques he recommends we choose for the assignment and because of that, majority if not all of the students who attended the seminar selected that technique because of the level of trust we (students) have in Jeff (lecturers), not because the decision tool had been critically analysed to reach that conclusion. A bias even before we started the selection of decision technique process. But reviewing a number of literatures now has proved that selecting the AHP technique was indeed a good choice.

  3. Hey Daniella, I as well think that we were biased right from the start. If we think about the first exercise during the 1st day of lectures. Jeff asked us to pick one site based on a 45 min analysis. Since then, we were bias, in my opinion. And what is more, I think that was done on purpose :)

  4. I had a think about this entry and I guess we all agree that we can’t eliminate bias. On one of the other blogs someone wrote that we should learn how to limit bias instead. This is a good idea and I would add to that, that instead of being taught how to make robust decisions, wouldn’t it be better to know how to make satisfactory decisions? I would imagine that it’s easier to master – it’s like: robust decision = very very good decisions, satisfactory = good decisions – seems to be easier to achieve. At the end of the day, I don’t need to get the best result, I just want not to fail.
