まとめ
党派主義者は最初は 集団内の情報を好むが 時間の経過とともに 信頼できる情報源を信頼するようになり 外部からのフィードバックがあれば 偏見を克服する. これは政治情報の処理における ベイジアン学習のダイナミクスを示しています
科学分野:
- 社会心理学
- 政治科学
- 情報科学
背景:
- 政治的誤った情報と信念の偏差は しばしば動機づけられた推論に起因します
- 別の見解では 党派主義は 情報の信頼性を高める ヒューリスティックとして使われます
- これらの動態を理解することは 政治的二極化に対処するために 極めて重要です
研究 の 目的:
- ダイナミックな政治環境で情報処理の競合する説明をテストする.
- 経験とフィードバックで 偏見を克服できるか調べる
- 情報源の信頼性に関する学習プロセスに影響を与える要因を特定する.
主な方法:
- 3つの実験では グループ内とグループ外からの メッセージを受け取りました
- ソースの信頼性を示すために外部からのフィードバックが提供されました.
- 異なる情報源からの参加者の組み込みは,時間とともに追跡されました.
主要な成果:
- 参加者は当初,党派的偏見を示し,特に感情的偏向が高いグループ内の情報源を好みました.
- 経験とフィードバックによって このバイアスは減り 参加者は党派関係にかかわらず 信頼できる情報源を優先することを学びました
- 情報の内容や情報源の種類 (党派的か中立的か) や金銭的なインセンティブは学習に影響を及ぼさなかったが,不確実性はそうだった.
結論:
- 信頼性の高い外部フィードバックで初期バイアスを克服するベイエスの学習ダイナミクスを示します
- 経験と正確性の動機は,個人の政治的所属に関係なく,信頼できる情報源を信頼することを学ぶことができます.
- これは,正確な情報評価を促進するメカニズムが二極化を緩和することを示唆しています.

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Confirmation Biases
7.2K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Bias

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

The Anchoring-and-Adjustment Heuristic
7.4K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Hindsight Biases
3.9K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
