The Diderot Effect: why we buy things we don’t need. Even so, we keep on buying new products, upgrading to the latest version, and filling our lives with possessions we don’t need. This tendency to overconsume is mostly caused by our natural need for betterment. We are constantly seeking improvement and progress in our lives, and this often translates into our purchasing habits. We believe that buying new things will make us happier or more fulfilled.

The Diderot Effect: why we buy things we don’t need. Even so, we keep on buying new products, upgrading to the latest version, and filling our lives with possessions we don’t need. This tendency to overconsume is mostly caused by our natural need for betterment. We are constantly seeking improvement and progress in our lives, and this often translates into our purchasing habits. We believe that buying new things will make us happier or more fulfilled.

A prime example of this is the story of Diderot, a French philosopher from the 18th century. Diderot's tale is a cautionary one, illustrating the dangers of falling into the trap of overconsumption. After receiving a gift of a beautiful scarlet robe, Diderot found that it clashed with the rest of his modest possessions. This led him down a path of buying new items to match the elegance of the robe. In a short amount of time, Diderot bought a new golden clock, a bronze sculpture, a console table, and more art pieces, ending up in debt. As he reflected on his situation, he famously said, “I was the absolute master of my old robe. I have become the slave of the new one.”

Diderot's experience resonates with many of us today. Our natural tendency is to always consume more, better, newer. We are constantly bombarded with advertisements and messages telling us that we need the latest gadgets, the trendiest clothes, and the most luxurious possessions. However, with a bit of self-control, it is possible to go from impulse buying to mindful consumption.

One of the first steps in curbing our overconsumption is to beware of the shiny toy syndrome. Buying a new shiny toy often only creates temporary satisfaction. We get a rush of excitement and novelty when we first make the purchase, but that feeling quickly fades away. We realize that the new item didn't actually bring us the happiness we were seeking. By becoming aware of this pattern, we can start to question whether we truly need the things we are tempted to buy.

Another strategy to avoid overconsumption is to create spending limits. A simple way to do this is to have a strict budget. By setting a specific amount of money that we can allocate towards discretionary spending, we can avoid going overboard with our purchases. This forces us to be more intentional and mindful about the things we buy. We have to prioritize and make choices based on what truly adds value to our lives.

Lastly, it is important to avoid consumption triggers. These triggers can come in many forms, such as advertisements, social media influencers, or even peer pressure. By recognizing these triggers and consciously choosing to resist their influence, we can regain control over our purchasing decisions. We can learn to act in a moderate, controlled, unrushed manner; to figure out what possessions will actually enhance our life, and which ones will simply empty our wallet. Taking the time to reflect on what we really need to feel safe and content can help us break free from the cycle of overconsumption.

In a similar vein, metrics-driven product development is hard. Teams often face two primary pathologies: nearsightedness and farsightedness. Nearsightedness occurs when a team is skilled at moving sensitive metrics, but their optimizations don’t translate to long-term business success. Farsightedness, on the other hand, happens when a team monitors metrics tied to their company’s long-term business success, but they’re unable to see how their work can move the metrics that matter. Both of these pathologies can hinder a team's ability to create sustainable value.

To combat these pathologies, teams need to develop "good vision" in the product development sense. This means having the capacity to make short-term bets that compound to create long-term business value. It may seem paradoxical to be simultaneously short-term and long-term oriented, but this is exactly what the world’s top companies do. They focus on both the immediate impact of their work and how it aligns with their long-term goals.

One key aspect of this is understanding the difference between lagging and leading indicators. Lagging indicators are the KPIs that actually matter for your business, such as revenue and customer retention. These metrics are often lagging and subject to external forces, making it difficult for product teams to directly impact them. On the other hand, leading indicators can be influenced by work, such as the percent of users that perform a certain action during a session. However, by themselves, they don't equate to business success. They can feel more like local optimizations than game-changing breakthroughs.

This is where the concept of the North Star metric comes in. The North Star metric acts as the bridge between leading and lagging indicators. It represents the ultimate measure of success for a product or company. By aligning their work with the North Star metric, teams can better understand how their efforts contribute to long-term business value. They can form hypotheses for how their work will move input metrics and how leading indicators influence lagging indicators. It's important to note that these relationships are dynamic and can change over time. What works now may not work in the future, so teams need to constantly reassess and adapt their strategies.

In conclusion, both the Diderot Effect and metrics-driven product development highlight the dangers of unchecked consumption and the importance of aligning short-term actions with long-term goals. By practicing mindful consumption and being aware of the factors that drive our purchasing habits, we can break free from the cycle of overconsumption. Similarly, by focusing on both the immediate impact and long-term business value, teams can navigate the complexities of metrics-driven product development. It may be challenging, but with self-control, intentionality, and a clear vision of success, we can find a balance between progress and contentment.
