How Humans Grew Acorn Brains: Understanding Long-Term Thinking and Planning in the Face of Crises

In today's fast-paced world, where instant gratification and immediate rewards reign supreme, it can be challenging for humans to think and plan for the long term. However, when it comes to long-term crises, such as the climate emergency, our ability to think ahead becomes crucial. Interestingly, our brains are equipped with both a Marshmallow Brain and an Acorn Brain, each serving a unique purpose in our decision-making processes.

The Marshmallow Brain, an ancient part of our neuroanatomy, focuses on instant rewards and immediate gratification. It is around 80 million years old and plays a significant role in our daily lives. We can see its influence when children are presented with a marshmallow and asked to delay eating it for a later, greater reward. The ability to resist immediate gratification is heavily influenced by socioeconomic factors, with those from wealthier backgrounds finding it easier to delay gratification.

On the other hand, the Acorn Brain, located in the frontal lobe just above our eyes, is a relatively new part of our neuroanatomy, only two million years old. It gives us the rare ability to think, plan, and strategize over long timeframes. This part of our brain is crucial when it comes to tackling long-term challenges like the ecological crisis. We need to tap into this unrivaled ability and become part-time residents of the future.

The human capacity to think long term is considered one of the brain's most stunning innovations. Evolutionary psychologists and archaeologists have offered several explanations for how our brains evolved this remarkable cognitive ability. One explanation is the survival skill of "wayfinding." Over millions of years, our ancestors developed the ability to navigate physical spaces during hunting or foraging expeditions. This skill required them to think and plan over long distances and timeframes.

Another enabler of long-term thinking is what is known as the "grandmother effect." Research suggests that the presence of grandparents, especially maternal grandmothers, is vital for reducing infant and child mortality. Older post-reproductive females provide essential childcare, knowledge, and support that increase the survival chances of the young. This relationship of trust and reciprocity works best when people know that the help they give now will likely be returned in the future, creating a sense of intergenerational time.

Lastly, the human genius for toolmaking has played a significant role in the development of our long-term planning abilities. As our brains evolved and we gained the ability to make complex tools, we also developed the capacity to plan and execute complex sequences of actions. This ability to plan for the future enabled us to engage in activities with long time horizons, such as crop rotation or building monumental structures like pyramids.

Now, let's shift our focus to understanding the rise of short-form video platforms like TikTok and ByteDance, which have revolutionized internet consumption habits. These platforms have captured the attention of millions of users worldwide and have become a compelling format for viewers and advertisers alike. But what factors contribute to their success?

ByteDance, the company behind TikTok, initially gained a notorious reputation for serving its users mindless click-bait content. However, the company quickly recognized the importance of superior classification and recommendation systems to diversify content beyond the popular categories of teen lip-sync and dance. Mobile internet usage differs significantly from desktop or laptop usage, with short sessions of less than 60 seconds being the norm. In this context, search-based methods are inefficient for matching users with content, as user-generated videos often lack accurate metadata.

Instead, recommendation engines that infer user preferences based on past behavior have become essential for delivering personalized content. ByteDance's success can be attributed to its ability to leverage recommendation algorithms to provide users with relevant and engaging content. This shift from "people looking for information" to "information looking for people" has transformed the way we consume content on these platforms.

In terms of revenue generation, advertising accounts for the lion's share, around 80%, of ByteDance's income. However, the company has diversified its revenue streams through various means, including extended businesses like games, paid knowledge, and e-commerce. Other sources of revenue include blue tick account verification fees and a system called "DOU+," where users or creators can pay to boost the visibility of their videos.

In conclusion, as humans, we possess both a Marshmallow Brain and an Acorn Brain, each serving a unique purpose in our decision-making processes. While our instinct for instant gratification may sometimes hinder our ability to think and plan for the long term, our Acorn Brain gives us the unparalleled capacity to become part-time residents of the future. To tackle long-term challenges like the climate emergency, we need to tap into this remarkable cognitive ability.

To harness our Acorn Brain effectively, here are three actionable pieces of advice:

1. Foster intergenerational relationships: Recognize the importance of grandparents and older individuals in providing vital support and knowledge that can benefit future generations. Encourage trust and reciprocity to create a network of mutual aid.

2. Invest in education: Teach individuals the value of long-term thinking and planning from an early age. Provide the necessary tools and resources for individuals to develop their Acorn Brain and make informed decisions.

3. Embrace technology thoughtfully: Leverage recommendation algorithms and personalized content delivery to enhance the user experience. However, be mindful of the potential pitfalls, such as the spread of misinformation or the reinforcement of existing biases.

By combining our innate cognitive abilities with the advancements in technology, we can navigate the complexities of the modern world and work towards a more sustainable and inclusive future.
