9 Cognitive Biases You Need to Avoid

📝 影片摘要

本單元深入解析九種常見的認知偏誤(Cognitive Biases),說明大腦如何透過「走捷徑」的方式來簡化決策過程,但這些捷徑往往會導致我們在判斷與決策上出錯。影片透過生活化的實例,如確認偏誤、錨定偏誤、達克效應等,解釋這些思維陷阱如何影響我們的財經思維與日常生活。最後,單元也提供了具體的克服策略,幫助學習者培養更客觀、全面的思考能力,避免落入認知偏誤的陷阱。

📌 重點整理

  • 大腦為了節省心力,會傾向使用捷徑,這雖有助於快速決策,卻容易產生認知偏誤。
  • 確認偏誤(Confirmation Bias):傾向尋找支持自己觀點的資訊,忽略反對意見。
  • 錨定偏誤(Anchoring Bias):過度依賴接收到的第一筆資訊(錨點)來做判斷。
  • 歸因偏誤(Attribution Bias):傾向將他人的行為歸咎於性格,卻將自己的行為歸咎於環境。
  • 月暈效應(Halo Effect):對某人或事物的單一好感會擴散到其他方面,影響客觀判斷。
  • 可得性偏誤(Availability Bias):根據容易回想的近期或極端資訊來做判斷,而非事實全貌。
  • 達克效應(Dunning-Kruger Effect):能力不足者往往會高估自己的技能,而專家反而較謙虛。
  • 鴕鳥效應(Ostrich Effect):刻意逃避負面或令人焦慮的資訊,反而可能導致問題惡化。
