How Humans Grew Acorn Brains: Finding Product Market Fit

When it comes to long-term crises, humanity has a less than exemplary record. Our response to the climate emergency has been painstakingly slow, despite the fact that its greatest impacts are yet to come. This sluggishness can be attributed to our Marshmallow Brain, an ancient part of our neuroanatomy that focuses our minds on instant rewards and immediate gratification. However, alongside the Marshmallow Brain, we possess a long-term Acorn Brain located in the frontal lobe that allows us to think, plan, and strategize over long timeframes.

To tackle long-term challenges like the ecological crisis, we need to tap into this unrivaled ability to become part-time residents of the future. But how did our brains evolve this remarkable cognitive ability? Evolutionary psychologists and archaeologists offer four main explanations.

The first is the survival skill known as "wayfinding." Over millions of years, our protohuman ancestors developed the capacity to navigate physical space during hunting or foraging expeditions. This spatial orientation and ability to navigate from place to place allowed them to plan and strategize over long distances.

The second explanation is the "grandmother effect." Research shows that the presence of grandparents, especially maternal grandmothers, reduces infant and child mortality. Older post-reproductive females provide vital childcare, knowledge, and support that increase the survival chances of the young. This relationship of trust and reciprocity, where help given in the present is likely to be returned in the future, is woven into the fabric of mutual aid.

The third explanation lies in our human genius for toolmaking. As our brains grew and we developed the ability to make complex tools, we also developed the capacity to plan and execute complex sequences of actions. This ability to plan enabled us to think and strategize over long time horizons, such as crop rotation or building monumental structures like pyramids.

Lastly, the ability to think long term is a stunning innovation of the human brain. Studies have shown that economics students who are taught that humans are essentially rational and self-interested creatures are more likely to act selfishly after completing their courses. This suggests that our innate capacity to think long term goes beyond mere self-interest and is deeply rooted in our biology.

Now, let's shift gears and explore how these concepts of long-term thinking and problem-solving apply to startups and finding product-market fit. Y Combinator advises startups to avoid solving problems that nobody has, as it is the most common failure mode. Good validation work involves conducting interviews and digging deep to find a problem that can be solved.

Technical founding teams should focus on ensuring they are solving a real problem rather than immediately building a solution. Building a product before validating the problem can lead to wasted time and effort. It is crucial to identify a problem that customers genuinely face and are willing to pay for a solution.

One example of this is the creation of analytics.js, a javascript library that solved a data-routing problem for the founders. Initially, they were unsure if there was a real business opportunity behind it. However, they decided to build a landing page to validate the problem it solved. The response was overwhelmingly positive, proving that there was a genuine need for this solution.

The key takeaway from this story is that if you're not 100% sure you're solving a real problem, you're most likely not. Validating the problem you're solving before investing time and resources into building a product is crucial for startup success.

To apply these insights to your own endeavors, here are three actionable pieces of advice:

1. Conduct thorough market research and customer interviews to identify and validate the problem you're solving. This will ensure that you're addressing a real need and increase the chances of finding product-market fit.

2. Prioritize problem validation over product development. It's better to spend more time understanding the problem before building a solution. This will save you from wasting resources on products that don't solve a genuine problem.

3. Create a feedback loop with your customers to continuously iterate and improve your solution. Actively listen to their needs and adapt your product accordingly. This will increase customer satisfaction and loyalty.

In conclusion, humans have evolved remarkable cognitive abilities to think and plan over long timeframes. This capacity, coupled with the ability to validate and solve real problems, is crucial for addressing long-term challenges like the ecological crisis. Whether it's on a societal or entrepreneurial level, tapping into our acorn brains and finding product-market fit requires a deep understanding of the problems we aim to solve.
