Wait, I thought data was supposed to help me be objective?
It’s true, working with data helps you to make better decisions, anchored in reality rather than opinion. But just because you’re working with data, doesn’t mean that your biases can’t distort how you’re seeing the world.
So what can I do about data bias?
The first step to overcome bias in your decision-making is to familiarize yourself with the most common types of data bias. To get you started, we’ve collected the six most common types of data bias, along with some recommended mitigation strategies.
1. Confirmation bias
You’ve probably encountered this underlying bias every day of your life. We all love being right, so our brains are constantly on the hunt for evidence that supports our prior beliefs. Even if we’re trying our best to be open to alternative ideas, our minds are pushing back towards the safety and comfort of our own first thoughts.
2. Selection bias
Selection biases occur when looking at samples that are not representative of the population. This can happen organically when working with small sets of data, or when the sampling methodology is not truly randomized.
3. Historical Bias
Historical data bias occurs when socio-cultural prejudices and beliefs are mirrored into systematic processes.
4. Survivorship Bias
It’s easier to focus on the winners rather than the runners-up. If you think back to your favorite competition from the 2016 Olympics, it’s probably pretty tough to recall who got the silver and bronze.
5. Availability Bias
Availability of data has a big influence on how we view the world—but not all data is investigated and weighed equally.
Wait, I Thought Data Was Supposed to Help Me Be Objective?
- It’s true, working with data helps you to make better decisions, anchored in reality rather than opinion. But just because you’re working with data, doesn’t mean that your biases can’t distort how you’re seeing the world. Cognitive biases are systematic errors in thinking, usually inherited by cultural and personal experiences, that lead to distortions of perceptions when making decisi…

- Selection biases occur when looking at samples that are not representative of the population. This can happen organically when working with small sets of data, or when the sampling methodology is not truly randomized.
Historical Bias
- Historical data bias occurs when socio-cultural prejudices and beliefs are mirrored into systematic processes. This becomes particularly challenging when data from historically-biased sources are used to train machine learning models—for example, if manual systems give certain groups of people poor credit ratings, and you’re using that data to train the automatic system, th…
Survivorship Bias
- It’s easier to focus on the winners rather than the runners-up. If you think back to your favorite competition from the 2016 Olympics, it’s probably pretty tough to recall who got the silver and bronze. Survivorship bias influences us to focus on the characteristic of winners, due to a lack of visibility of other samples—confusing our ability to discern correlation and causation.
Availability Bias
- Availability of data has a big influence on how we view the world—but not all data is investigated and weighed equally. Have you ever found yourself wondering if crime has increased in your neighborhood because you’ve seen a broken car window? You’ve seen a vivid clue that something might be going on, but since you probably didn’t go on to investigate crime statistics, it’s likely th…

- Averages are a great place to hide uncomfortable truths. Some data is convenient to visualize as an average, but this simple operation hides the effect of outliers and anomalies, and skews our observations.
Final Thoughts: Data Bias
- Working through our cognitive biases is an important part of working with and learning from data. Although data helps us see the world like never before—becoming aware of, and taking preventative measures against data biases is an important step to making better decisions with data.
