With regard to Johnson’s comment relating to Garnier’s research analysts, which of the following biases is most likely to be present in the analysts’ data?
选项：
A.Confirmation bias.
B.Availability bias.
C.Self-attribution bias.
解释：
A is correct.
Confirmation bias, a cognitive bias, is the tendency for people to misread evidence as additional support for an initial hypothesis. Confirmation bias is a potential bias for analysts conducting research. It is a form of resolving cognitive dissonance that described the tendency to search for, or interpret, information in a way that confirms the analyst’s prior beliefs. The additional information may not be analyzed in a rigorous way, but it can nevertheless appear to make the judgment or forecast more likely by sharing some of its general characteristics.
"john's comment on..." 是指 “only securities that are covered by Garnier’s research analysts and approved by the Private Wealth Investment Committee can be placed in a client’s portfolio.”这句么？为何不能从后边提到的confidence、proud..认为存在confidence bias，并从而选C呢
