Survivorship Bias in Start-Up Ideas: What to Consider
Written on
Understanding Survivorship Bias
When you turn on the television, it often seems like success is everywhere. You see entrepreneurs who have hit it big, celebrated musicians, bestselling authors, and acclaimed filmmakers. However, the stories of failure are seldom highlighted. Why is this the case?
For one, there's a practical reason: covering all the unsuccessful endeavors would be an overwhelming task, as most people prefer to hear uplifting stories of triumph. Additionally, we naturally gravitate towards narratives of those who have achieved fame, as they resonate more with the general public.
This phenomenon is known as "survivorship bias." It refers to a cognitive error where we focus excessively on successful outcomes while overlooking failures. This skewed perception can lead us to overestimate the likelihood of success and underestimate the risks of failure.
The Implications of Survivorship Bias
Consider this next time a former classmate presents you with a promising start-up idea. While it's important not to dismiss their enthusiasm, it’s crucial to remain mindful of survivorship bias when evaluating the business opportunity and deciding how much to invest. This venture could be the next big thing, or it might not pan out.
The Mechanics of Survivorship Bias
Our minds are wired to recognize patterns, which often leads us to find comfort in stories of success.
Examples Across Different Fields
- Finance: Investors often look at the performance history of asset managers, assuming that past success guarantees future results. However, they might overlook poorly performing funds that have been closed and are no longer part of the data.
- History: A notable example is from WWII, where analyst Abraham Wald advised reinforcing parts of returning aircraft that showed no damage, assuming that these areas were likely hit on planes that did not return.
- Entrepreneurship: Successful startups dominate media coverage, but the stark reality is that a significant number of startups fail within their initial years. Unicorns are termed as such for a reason—they are rare.
- Science: Publication bias can skew the research landscape, favoring studies with significant findings while neglecting those with inconclusive or negative results, which could also provide valuable insights.
Consequences of Ignoring Survivorship Bias
Neglecting this bias can lead to overly optimistic views on success rates, flawed strategies, and decisions based on incomplete information. In business, this may result in underestimating the risks associated with new ventures. On a broader scale, such oversight could lead to ineffective policies that fail to meet the needs of all stakeholders.
Strategies to Combat Survivorship Bias
To avoid falling prey to survivorship bias, the first step is to recognize its existence and be aware of your inherent biases. By staying alert, you can be more cognizant of potential risks.
When assessing a project, actively seek out information about those who did not succeed, broaden your dataset, and maintain a critical outlook toward narratives that only highlight success stories.
A more comprehensive perspective will enable you to make informed decisions and manage your expectations realistically. Ultimately, regarding your friend’s start-up idea, I’m not suggesting you shouldn't pursue it. Conduct thorough due diligence, and if you feel confident after considering survivorship bias, then go for it! After all, while there’s no success without risk, you can navigate those risks wisely.
