Vierordt’s Law: Unveiling the Bias in Decision-Making


In the realm of decision-making, understanding the underlying psychological biases that influence our choices is paramount. One such bias is Vierordt’s Law, which sheds light on how humans tend to misjudge the passage of time. Named after the German psychologist Karl Vierordt, this mental model states that individuals perceive shorter durations as longer and longer durations as shorter. Recognizing the presence of Vierordt’s Law in our lives is essential to making rational decisions and avoiding the pitfalls of biased thinking. In this blog post, we will explore the concept of Vierordt’s Law, examine its prevalence in various contexts, dissect the biases that contribute to it, and offer practical strategies to counteract its influence.

Understanding Vierordt’s Law

Vierordt’s Law is rooted in the perception of time, an intricate aspect of human psychology. According to Vierordt’s observations, individuals tend to overestimate short periods of time and underestimate longer durations. For example, waiting for five minutes may feel like an eternity, while an hour-long conversation can seem to pass quickly. This bias can affect decision-making processes by distorting our perception of time frames and influencing our evaluations of options.

The Role of Vierordt’s Law in Decision-Making

Vierordt’s Law has implications across various domains, from personal life decisions to business scenarios and public policy-making. Let’s explore three distinct examples to illustrate its occurrence and the irrational decisions it can lead to.

  1. Personal Life Decisions: Imagine a person who wants to adopt a healthier lifestyle. They set a goal of exercising for 30 minutes each day. Initially, the first few minutes of exercise might feel longer, leading them to perceive the entire 30-minute session as an arduous task. This distorted perception can discourage them from continuing their exercise routine, as they perceive it as more time-consuming than it actually is.
  2. Business Scenarios: In business negotiations, Vierordt’s Law can influence decisions regarding the allocation of time and resources. For instance, a company may disproportionately focus on short-term gains rather than long-term investments. This bias can lead to missed opportunities for growth and innovation, as the allure of immediate rewards distorts their perception of the long-term benefits.
  3. Public Policy-Making: Vierordt’s Law can also impact the formulation of public policies. A government faced with a complex issue might rush to implement quick-fix solutions that address immediate concerns, overlooking the potential long-term consequences. By succumbing to Vierordt’s Law, policymakers may prioritize short-term gains without fully considering the broader impact on society.

Biases Contributing to Vierordt’s Law

Vierordt’s Law is intertwined with several cognitive biases that shape our decision-making processes. These biases include the availability heuristic, anchoring bias, and cognitive overload.

  1. Availability Heuristic: The availability heuristic leads us to rely on easily accessible information when making decisions. In the context of Vierordt’s Law, our experiences of shorter durations are more vivid and memorable, making them easier to recall. Consequently, we give them more weight when evaluating the passage of time, reinforcing the bias.
  2. Anchoring Bias: The anchoring bias influences our decision-making by relying heavily on an initial reference point. When estimating time durations, we often anchor our judgments on immediate cues or past experiences. This bias can distort our perception, leading to the inaccurate evaluation of time intervals.
  3. Cognitive Overload: Human cognition has limitations, and when we are overwhelmed with information or tasks, our perception of time can become distorted. Cognitive overload can amplify the effects of Vierordt’s Law, making it more likely for us to succumb to biased judgments.

Psychological Underpinnings and Mitigation Strategies

Vierordt’s Law is connected to several psychological phenomena, such as attentional processes, memory biases, and emotional states. Recognizing these interconnections can help us identify when we might be falling prey to this bias. Here are practical strategies to avoid the influence of Vierordt’s Law:

  1. Time Framing: When faced with decisions involving time, consciously reframe the duration to neutralize the bias. Breaking longer time periods into smaller, manageable intervals can help combat the perception of elongated durations. By mentally segmenting time, you can maintain focus and engage in a more accurate evaluation.
  2. Self-awareness and Monitoring: Cultivate self-awareness by paying attention to your perception of time in different situations. Take note of instances when you feel time is passing slowly or quickly, and reflect on the factors influencing these judgments. Monitoring your own biases can help you recognize when Vierordt’s Law may be distorting your decisions.
  3. Objective Metrics: Incorporate objective metrics into your decision-making process to counteract subjective biases. By relying on verifiable data and measurements, you can ensure a more rational evaluation of options. Avoid solely relying on personal experiences or emotions, which can be subject to Vierordt’s Law.


Vierordt’s Law reveals how our perception of time can lead to biased decision-making. By understanding this mental model and its prevalence in various contexts, we can become more aware of our susceptibility to its influence. Acknowledging the biases that contribute to Vierordt’s Law and implementing practical strategies can empower us to make more objective decisions. Remember, time perception is subjective, but by actively avoiding this mental trap, we can navigate decision-making processes more effectively and align our choices with our best interests.
