问题如下：
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.
这道题目关于confirmation basis和availability basis的区别没看明白。
看助教回答说分析师支持Johnson自己的股票所以是confirmation basis，如果是这样我理解。因为说明分析师confirm了Johnson已有的决定。
但题目中没说分析师支持的是Johnson已经有的股票啊，只是说分析师看好的股票Johnson愿意多承担风险。这不就是相当于Johnson愿意接受分析师推荐的股票，是availability basis么？
