Understanding Cognitive Biases in Tech Startups: A Guide
Written on
Chapter 1: Introduction to Cognitive Biases
Humans inherently possess biases, which have played a significant role in our evolution. In the realm of business, recognizing these biases is crucial to making sound decisions. This article delves into three prevalent cognitive biases and offers methods to mitigate their effects.
What Are Cognitive Biases?
Cognitive biases refer to systematic deviations from rational judgment, leading to illogical conclusions about people and situations. These biases can skew our decision-making process, often prioritizing assumptions over objective reasoning. Below are a few common biases and strategies to counteract them.
Section 1.1: Sunk Costs Bias
Sunk costs bias, as described by Arkes & Blumer, occurs when individuals are more inclined to persist in an endeavor after investing resources—be it time, money, or effort. This bias can lead to a preference for continuing a project based on past investments, even when the potential future benefits are minimal.
In the context of tech projects, sunk costs bias can manifest when a product development timeline extends beyond expectations. Instead of pivoting or scaling back, teams may feel compelled to press on, influenced by their prior investments. Similarly, when a product fails to generate anticipated revenue, teams might opt to allocate more resources in an attempt to salvage it.
How to Avoid It
To combat sunk costs bias, it's advisable to break projects into smaller, manageable stages, soliciting frequent feedback from end-users. Long durations without product releases can exacerbate this bias. If sunk costs have already become a concern, it requires considerable discipline to abandon an idea, as loss aversion may come into play.
Chapter 2: Planning Fallacy
Tversky & Kahneman characterize the planning fallacy as the tendency to underestimate the time required to complete a task due to an overreliance on optimistic forecasts. This bias often surfaces when individuals project overly positive outcomes, sometimes due to external pressures, such as a CEO's expectations for expedited project timelines.
In tech projects, the planning fallacy can occur during both daily task estimations and broader project planning. It is especially prevalent in the waterfall project management approach, where an overly optimistic timeline is set that often fails to account for unforeseen challenges.
How to Avoid It
To mitigate the planning fallacy, teams can base their time estimates on historical data and acknowledge the inherent challenges in providing accurate predictions. Alternatively, they can express estimates in terms of complexity rather than time, akin to using story points in Agile methodologies.

Chapter 3: Survivorship Bias
Survivorship bias, as defined on Wikipedia, refers to the error of focusing on successful entities while ignoring those that did not survive a selection process. For instance, aspiring millionaires might mimic the paths of existing wealthy individuals without considering those who attempted the same but failed.
In tech, companies often gather feedback from their existing customer base to inform product development. However, this practice can lead to a skewed perspective as it overlooks customers who did not convert or engage with the product.
How to Avoid It
To counteract survivorship bias, it is essential to identify stages in the customer acquisition process where potential users drop off. Gathering insights from these individuals can provide valuable perspectives that are often overlooked. Additionally, it’s crucial to analyze any conclusions drawn from data that may misattribute success to surviving customers.

Conclusion
This article has highlighted three cognitive biases that can negatively impact tech startups and presented strategies to mitigate them. While numerous cognitive biases exist, being aware of them is the first step toward making informed decisions. As you explore these concepts further, remember that overcoming biases is challenging, but awareness is crucial for improvement.
