问题如下：
Blackstone, a financial institution, is currently facing a large potential risk. Blackstone had no choice but to consult with financial experts in outside think tanks. However, Blackstone found that some experts were not willing to publish a point of view that contradicted other experts in the think tank. Which of the following biases describes this phenomenon?
选项：
A. Huddle bias.
B. Presentation bias
C. Context bias.
D. Anchoring bias
解释：
A is correct.
考点：Biases and challenges for scenario analysis
解析：Huddle bias：一个群体中的人们倾向于发表相同的观点，避免互相矛盾的观点。这与本题中的情景相一致。因此选A。
Presentation bias：该偏误描述的是呈现信息的顺序，会影响别人的看法、建议。
Context bias： 描述的是问题呈现方式的不同，可能会影响被问者的反应、回答。
Anchoring bias：描述的是过度依据已有信息，比如自己先前的经验，而对现在的情况轻易做出判断。
BCD选项都与本题情景不符
这个知识点在讲义那一页？
