Your brain is lying to you—in predictable, well-documented ways. Here's how to catch it.
Cognitive biases are mental shortcuts (heuristics) that our brains use to simplify information processing. While these shortcuts are often useful, they can also lead to systematic errors in thinking. The pioneering work of psychologists Daniel Kahneman and Amos Tversky identified dozens of these biases, which can undermine even the most experienced leader's judgement.
For women leaders, understanding and mitigating these biases is a critical step toward making more effective, impartial, and strategic decisions.
What it is: The tendency to search for, interpret, favour, and recall information in a way that confirms your preexisting beliefs.
How it shows up: A leader who believes a certain project will succeed may unconsciously seek out data that supports this belief while dismissing contradictory evidence, leading to a failure to recognise warning signs.
How to avoid it: Actively seek out disconfirming evidence by asking, "What information would prove me wrong?" Appoint a devil's advocate on your team, or use a "red team/blue team" exercise.
What it is: The tendency to rely too heavily on the first piece of information offered (the "anchor") when making decisions.
How it shows up: The first number mentioned in a salary negotiation, the initial sales forecast, or the first opinion voiced in a meeting can all act as powerful anchors that unduly influence the final outcome.
How to avoid it: Be aware of the anchor. Before entering a negotiation or discussion, do your own research and come with your own independent assessment. Consciously re-anchor the conversation to a different reference point if needed.
What it is: A mental shortcut that relies on immediate examples that come to mind when evaluating a topic or decision.
How it shows up: A leader who has recently read about a cybersecurity breach may overestimate the likelihood of their own company being hacked. We tend to give more weight to recent performance when conducting employee reviews.
How to avoid it: Seek out base-rate information instead of relying on vivid anecdotes. Keep detailed records so evaluations are based on comprehensive data, not recency.
What it is: The tendency for an initial positive impression of a person to positively influence your opinion in other areas.
How it shows up: A leader might assume that a charismatic, well-spoken employee is also competent and strategic, even without evidence. This can lead to biased hiring decisions and unfair promotions.
How to avoid it: Evaluate specific traits independently using structured scorecards. Involve multiple raters in evaluation processes.
What it is: The tendency to continue an endeavour because of previous investment, even when it's clear the endeavour is failing.
How it shows up: A leader may continue pouring resources into a failing project because they've already invested so much, rather than cutting losses and reallocating.
How to avoid it: Focus on future costs and benefits. Ask yourself, "If I were starting from scratch today, would I still invest in this?" Bring in an outside perspective for objective assessment.
Individual awareness is a good start, but creating a structured process is even more effective:
Cognitive biases are an inherent part of the human condition, but they don't have to dictate your leadership decisions. By understanding the most common biases, actively seeking to counteract them, and building structured decision-making processes, you can enhance your ability to make clear, rational, and effective choices.
A skilled leadership coach can help you identify your specific blind spots and build the self-awareness that leads to better decisions.
