Goodhart's dilemma is a paradox stating that when a measure becomes a goal , it loses its effectiveness as an indicator. This phenomenon can have negative consequences in the business, educational, and personal spheres.
Simply put, this means that when we focus too much on a metric, we can end up manipulating or distorting that metric to achieve the desired result.
A concrete example of this phenomenon is the TikTok platform. As many of you know, TikTok is a platform based on the creation and distribution of short videos, which tend to go viral. The platform uses an algorithm that recommends videos to users based on their viewing history. As a result, content creators have focused on creating videos that appeal to the algorithm, leading to an increase in dance videos, challenges, and other content that is easy to consume and grows within the network.
This change in TikTok's content has been criticized by some users, who argue that the platform has lost its original quality, becoming filled with "garbage" content of little value.
Another example of Goodhart's dilemma is the case of businesses. For example, a company might focus on increasing sales of a specific product, which could lead to a reduction in the quality of other products or services. Or, a company might focus on reducing costs, which could lead to a decrease in product quality or efficiency in service delivery.
Tips to avoid the Goodhart dilemma
To avoid Goodhart's dilemma, it is important to keep the following tips in mind:
- Use multiple measures. Don't focus on just one measure, but on a set of measures that provide a more complete picture of the situation.
- Consider the consequences. Before setting a goal, think about the possible consequences of achieving it.
- Use the measure flexibly. Don't use the measure inflexibly, but adapt it to the circumstances.
Goodhart's dilemma is an important phenomenon to consider when setting goals and measuring progress. We must be aware of how our measurements can distort our objectives and ensure we don't lose sight of what truly matters.
