Issues with Predictive Analytics

Marketers should be using predictive analytics to help plan out their tactics, specifically their content marketing.

But what are the issues with predictive analytics when it comes to marketing planning?

Predictive analytics is a hot topic. We spend a lot of time talking about how beneficial predictive analytics can be to our business decisions but we also need to acknowledge that there are a few things that can go wrong. Predictive analytics is based on mathematics, on taking existing data and forecasting it forward. So, what are the potential pitfalls to be aware of? 

What are the issues with predictive analytics?


Black Swan Events

Predictive analytics can run into some serious problems with any kind of black swan event. A Black Swan Event is something unforeseen on the forecast level. For example, it can be political upheaval, natural disaster, stock market crash, or something that can have a materially adverse impact on a forecast. But there’s no way to predict a Black Swan Event. That said, you can factor such historical events into your algorithm, knowing that the anomaly will throw off the analysis.

Evolving Landscape

More conventionally, predictive analytics can go wrong, particularly in the domain of marketing, is predicting things where there is a change in the overall landscape that is very complex. A really straightforward example is this; about 18-24 months ago we started seeing social engagement changing because people were taking conversations elsewhere, away from the big networks like Facebook. Edison Research just released data that Facebook usage was down year over year and the research stated the other social networks didn’t pick it back up. So where did all that go? It’s going to messaging apps such as Whatsapp, Kik, Tango, WeChat, etc. If you’re building predictive forecasts based on this data you may not see this trend clearly, depending on how long your window of predictive training data is. I may not be able to understand what is going on in there. Those are nuances you’ll have to be aware of and that’s something that you have built into your model.

Building Algorithms without Domain Expertise

The biggest danger for marketers is having someone build or analyze any kind of predictive model without domain expertise. This means building the model using artificial intelligence, machine learning, and algorithms, without really understanding what they do. You can run an algorithm on a data set and get output but unless you know how that algorithm was constructed your insights might not be accurate. Marketers need to have at least a high-level understanding of the puzzle pieces to know if the output is accurate or if it needs to be adjusted. We as humans have to provide judgment, insight, and context to all the predictions that we do. Otherwise, we’re going to just create a massive mess.

Not Using Human Judgment

Predictive analytics is a lot like GPS.  If you forecast your drive with your data, you are the ones still driving the car using the data to drive it. But if the data is not good, or the conditions change, or the model has been built in is constantly tuning, you’re going to go off the road.


On the other hand, you also don’t want to ignore the data. Predictive analytics, like any form of data analysis, still needs human judgment. Your GPS won’t tell you to stop at a red light, but from experience, you know that you should stop to avoid an accident. The data you get from your forecast will be useful for planning but should also be blended with your institutional knowledge, industry expertise, and experience.

Those are the main issues you can run into with predictive analytics. Black swan events, evolving landscape, lack of domain expertise, or lack of human judgment. All of that aside, having the capability to run forecasts on your data is really powerful once you have a handle on it.

While there are issues with using predictive analytics it can still be a powerful tool. Reach our disadvantages of predictive analytics posts to make sure you’re setting yourself up for success. You can find the post here:
