Final answer:
The most supporting detail is the explanation of how misinformation can become embedded in societal beliefs due to a lack of critical examination of sources combined with the perpetuation of biases and personal experiences like misattribution.
Step-by-step explanation:
The detail from the passage that best supports the idea that people sometimes trust sources containing misinformation is the explanation on how misinformation can spread through various forms of media and become a part of societal beliefs, without people questioning the original source. For instance, the passage uses the common belief that cold weather causes colds as an example of misinformation perpetuated through generations, despite it being medically inaccurate since colds are caused by viruses. The passage also mentions confirmation bias and the Dunning-Kruger effect, where individuals might overestimate their knowledge or understanding of a topic, potentially leading to misplaced trust in unreliable sources.
Another contributing factor is the bias by a selection of sources, where media outlets might present a particular viewpoint by selectively quoting experts or testimonials that align with their agenda. This mechanism can lead people to trust the apparent 'expert' testimony without considering potential biases or the lack of diverse perspectives. Moreover, personal experiences such as errors in memory recall, like the misattribution of experiences or suggestibility, can contribute to people trusting misinformation.
