- [Behavioral Finance and Investing: Are you Trying Too Hard?](https://alphaarchitect.com/behavioral-finance-and-investing-are-you-trying-too-hard/): Everyone makes mistakes\. It’s part of what makes us human\. Because humans understand their actions are sometimes flawed, it was perhaps inevitable that the field of psychology would develop a rich body of academic literature to analyze why it is that human beings often make poor decisions\. Although insights from academia can be highly theoretical, our everyday life experiences corroborate many of these findings at a basic level: “I know I shouldn’t eat the McDonalds BigMac, but it tastes so good\.” Because we recognize our frequent irrational urges, we often seek the judgment of experts, to avoid becoming our own worst enemy\. We assume that experts, with years of experience in their particular fields, are better equipped and incentivized to make unbiased decisions\. But is this assumption valid? A surprisingly robust, but neglected branch of academic literature, has studied, for more than 60 years, the assumption that experts make unbias decisions\. The evidence tells a decidedly one\-sided story: systematic decision\-making, through the use of simple quantitative models with limited inputs, outperforms discretionary decisions made by experts\. This essay summarizes research related to the “models versus experts” debate and highlights its application in the context of investment decision\-making\. Based on the evidence, investors should de\-emphasize their reliance on discretionary experts, and should instead approach investment decisions with systematic models\. To quote Paul Meehl, an eminent scholar in the field, “There is no controversy in social science that shows such a large body of qualitatively diverse studies coming out so uniformly in the same direction as this one \[models outperform experts\]\.”
