For example, imagine that you suspect your computer has been hacked. Every time it stalls or has a little error, you assume that it was triggered by a hacker and that your suspicions are valid. This bias plays an especially big role in rivalries between two opposing views. Each side partitions their own beliefs in a logic-proof loop, and claims their opponent is failing to recognize valid points. Outwitting confirmation bias therefore requires exploring both sides of an argument with equal diligence.
比如说，假设你怀疑自己的电脑受到了黑客攻击，那么它每次死机或出个小错，你都会认定是由黑客引起的，而且你认定自己的怀疑正确无误。这种偏差在两种敌对观点的对抗中会起到尤其重要的作用。每一方都会把自己的观点隔离出来，认为其在逻辑上无懈可击，并声称他们的对手忽略了某些要点。所以，要克服“确定性偏差”，就要以同样的努力认真探究论点的正反两面。
Similar to confirmation bias is the overconfidence bias. In an ideal world, we could be correct 100 percent of the time we were 100 percent sure about something, correct 80 percent of the time we were 80 percent sure about something, and so on. In reality, people's confidence vastly exceeds the accuracy of those judgments. This bias most frequently comes into play in areas where someone has no direct evidence and must make a guess - estimating how many people are in a crowded plaza, for example, or how likely it will rain. To make matters worse, even when people are aware of overconfidence bias, they will still tend to overstate the chances that they are correct. Confidence is no prophet and is best used together with available evidence. When witnesses are called to testify in a court trial, the confidence in their testimony is measured along with and against the evidence at hand.
与“确定性偏差”相类似的是“过度自信偏差”。在一个理想的世界，当我们百分之百地确信某件事时，我们就百分之百地正确；当我们百分之八十地确信某件事时，我们就百分之八十地正确，以此类推。但在现实中，人们的信心却大大超过了其判断的准确度。在一个人缺乏直接证据而必须要作出某种猜测的情况下，这一偏差就最有可能起作用，比如，估计一个拥挤的购物广场有多少人，或下雨的可能性有多大。更糟糕的是，即使人们意识到自己有过度自信的偏差，他们还是会高估自己的正确率。光靠自信是无法进行准确预测的，只有在切实证据的基础上，自信才能发挥最大的作用。当法庭传唤目击者出庭作证时，对他们证词的信任度是通过已经获取的相符或相反的证据来度量的。
The availability bias is also related to errors in estimation, in that we tend to estimate what outcome is more likely by how easily we can recount an example from memory. Since the retention and retrieval of memories is biased toward vivid, sensational, or emotionally charged examples, decisions based on them can often lead to strange, inaccurate conclusions.
凭借回忆某一例证的难易程度来推测哪种结果更可能出现。由于记忆的留存和重拾会因为事件的生动与否、震撼程度和情感触动程度的不同而产生偏差，那么，基于这些记忆所作出的决定也往往会是奇怪或不准确的结论。
In action this bias might lead someone to cancel a trip to, for example, the Canary Islands because of a report that the biggest plane crash in history happened there. Likewise some people might stop going out at night for fear of assault or rape.
在具体行为中，这种偏差可能会使某人取消比如前往加那利群岛的行程，因为有报道说，史上最惨重的空难就发生在那里。同样，人们也可能因惧怕遭到人身侵犯或者强暴而不敢再在晚上出门。
