🔎 Interesting reads you probably missed

Make your product based on data, not opinions

John McTavish explains that experimentation is a core skill for product managers or early-stage founders. He dives into experiment best practices and how they apply to startups at each stage.

The more wrong you are at the beginning, the more right you become later.

One of the key benefits of experimentation is preventing incorrect assumptions from being fully implemented. It saves you the trouble of building something wrong and spending too much time on the wrong objectives.

Being wrong is a learning and decision-making tool that saves you time and money long-term.

Increase A/B testing power by combining experiments

Article Zezhong Zhang from eBay about a powerful meta-analysis method called “weighted z-test”.

The weighted z-test brings several benefits at zero cost. By leveraging all the collected samples in different experiments, the z-test makes the combined readout more powerful, producing the effectiveness of a much larger and more robust experiment.

📄 Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty

If you ask 75 research teams whether increased immigration decreases public support for the welfare state, you will get very different results. And … it is not clear why the results differ.
