Confirmation/Escalation Bias

Have seen some questions on Confirmation/Escalation Bias. Can someone enlighten me on these? Are there any other biases related to investors?

I have seen confirmation/escalation bias in some questions as well, but I don’t think they were covered in the 2011 curriculum. You can find a full list of all the biases in the behavioral finance section in reading 57.

@donknow1987: Just curious- Are you using 2010 or 2011 materials?

@JonnyKay I saw this question somewhere…probably Schweser Vol 2 2011 !
