The Major Behavioral Biases Influencing Your Investment Decisions 
 

By Jason Voss, CFA

You may not believe it, but science has proven that you and I are biased and often make irrational decisions. That we are all biased is interesting … but even more interesting is the question of how do we avoid these biases to become better investors? Recognizing the major biases is the first step in learning how to avoid them in your investing. In the article The Major Behavioral Biases Influencing Your Investment Decisions, author Jason Voss outlines the major biases that often impact investing decisions.

Some of the topics covered in the article include:

  • The 10 core biases that merit your attention
  • Which of the biases impact investors most often
  • Why behavioral biases are not hardwired

Despite best efforts to remain neutral in investing, biases influence decisions without many even realizing. You’ll benefit by keeping these 10 core biases in mind as you tackle investment decisions. Be honest with yourself, as you are the only witness to these errors. Admitting that you are susceptible to behavioral biases is the first step to learning how to avoid them.

Making Better and More Rational Decisions 
 

By Annie Duke

Former professional poker player Annie Duke has used her unique experience to become an expert corporate consultant and author on the behavior of decision-making. In a conversation with AAII Journal editor Charles Rotblut, she discusses the self-serving bias we all have that leads us to attribute good outcomes to our decision process and bad outcomes to external factors. This hurts our ability to improve our decisions going forward, which can be especially harmful for individual investors.

In the interview “Making Better and More Rational Decisions” Duke also explains how our tendency to notice all the things that agree with us prevents us from seeking out differing opinions, which can be valuable for pointing out something about our investing decisions that we haven’t thought about before. She also suggests that thinking about the various ways the future could play out can help you prepare for unfavorable outcomes and avoid irrational decisions.

When investing, recognizing when a future version of ourselves might make an irrational decision can enable us to do things, such as setting a loss limit, to protect ourselves from making those irrational decisions. In this article you’ll find more tips to improve the odds of making rational decisions with your finances and investments.
