Predict A/B test results using ancient Indian astrology

We at VWO have a mission to help marketing and product teams reduce the time and effort required to figure out what works best for their business and what doesn’t. In 2010, we pioneered the Do-It-Yourself Visual Editor for business teams for editing webpages and creating their variations for A/B tests without involving IT teams. That innovation cut the effort to launch an A/B test from weeks to hours and the A/B testing industry hasn’t been the same ever since.

But, as anyone who has run an A/B test knows, you still have to wait for weeks in order to start getting statistically significant results about which version is better.

We’ve been wondering if there’s a way to cut this wait period as well. Wouldn’t it be wonderful if there was a way to instantly know which version is going to win without waiting weeks or months for the data to arrive?

Can AI help?

The first research direction we turned to was the booming AI technology. You would have certainly heard about neural networks, machine learning, and data science. Could one such technique help us? If neural networks can drive cars today, perhaps they can also predict which website version is better.

Over the last few years, we tried several techniques and invested a lot of money in trying to get one of the AI techniques to work. We did make some progress when a couple of months ago, we launched an AI-powered website copywriter that helped marketers come up with new alternative headlines, CTAs, and product descriptions to test.

But, unfortunately, similar AI-based techniques didn’t perform satisfactorily on the prediction of A/B test results. It seems driving cars, beating the World Go champion, and detecting tumors is an easier problems than predicting which website design is going to be a better choice.

Enter IA

As we were about to almost give up on our dream project, someone pointed us to the elephant in the room: astrology. Our first reaction was to dismiss this absurd suggestion immediately. We’re a skeptical bunch and there’s no place for such pseudoscience in a serious business like ours.

But we were desperate and decided to give this totally absurd idea one last shot. We were told that millions of people across the world predict all sorts of phenomena using techniques like horoscopes, or Tarot cards. If people are using a technique to predict whether their marriage will succeed or not, can’t it be used to predict whether the A version is better than the B version?

After looking at the cost-benefit equation, we decided to do a small pilot. If, as we predicted, astrology didn’t work we’ll just lose some investment and time. However, if it did work, it would change the marketing and user research industry forever.
So, in all earnestness, we kickstarted the pilot. After doing initial research on the most predictive astrology technique, we settled on Indian Astrology (IA). Particularly, we settled on parrot astrology. What gave us confidence in it was that there’s even a Wikipedia page on it.

In parrot astrology, an astrologer lays out multiple options in front of a caged pet parrot. When the parrot is let out of the cage, it picks one of the options as the prediction. Simple and straightforward. We loved it already.

What we did for our pilot is the following:

• Take 100 A/B tests from our database where there was a clear, statistically significant winner (either A or B)
• Print their screenshots
• Recruit an Indian astrologer with a parrot and have the parrot pick between the pairs of screenshots across 100 trials (one for each A/B test)

Our null hypothesis was that the parrot wouldn’t be able to pick better than the random chance. That is, the parrot should pick the correct winner and the loser each roughly with a 50% chance.

However, to our astonishment, the parrot picked the winner 80 times out of 100. Using any standard binomial calculator (either frequentist or Bayesian), you’ll quickly find out that the chances of that happening are close to nil. Indian Astrology really worked!

We’re obviously onto something here. We soon plan to write a scientific paper on this and submit our findings in a top journal. It’s all very exciting and mysterious. How does the parrot know which version works best? Well, we don’t know that but it shouldn’t prevent us from using the technique in the real world (just the same way we still don’t know why deep learning is so effective at various kinds of problems but it’s used widely).

Get early access to parrot-powered A/B test prediction

We’re actively trying to scale the pilot with the eventual goal of making it available for all businesses in the world via a simple user interface inside VWO or via an API.  The main challenge is finding enough parrots and making sure we’re doing this ethically. Once we do that, any business in the world will be able to rapidly converge on optimal user interface without the need to do any A/B testing.

We have some slots for people who want early access to this technology. If you want to give it a shot, email us here: aprilfools@vwo.com.

Wait, what?

Well, didn’t we say we’re a skeptical bunch? It turns out there’s no scientific evidence that astrology works. Moreover, we strongly condemn the caging of any bird or animal for anything other than clinical or medical research (even in clinical research, we wish computational and physical models increasingly replace actual animals).

If you were excited about the prospect of prediction of A/B test results, you’re not alone. We’re excited about the same thing and even though parrot astrology doesn’t work, we’re committed to continue making progress towards helping business teams achieve a higher probability of success in each of their A/B tests.

After launching an AI-powered website copywriter last year, we recently launched an AI-powered heatmap predictor. After you enter your webpage URL, we take a screenshot and use deep learning to predict the distribution of clicks on the website. This can help you spot obvious dead zones or distractors on your website even before you make it live or use a heatmap tool on it.

This tool is free to use. So feel free to try it as many times on as many websites.

We’re sorry for giving you hope that you can get rid of A/B testing, but hope you had fun reading the post 🙂

Happy April Fool’s day!
