Not So Random Software #42 – The End of Average

Hello everyone and welcome back to Not So Random Software!

This week I have been thinking about diversity and how to reconcile the problem of deviating from the expected norm when hiring in business. I am sold already; You don’t need to convince me that diversity is a good thing to aim for. Said that I am also mindful that my actions alone will not be enough if I don’t take into consideration the business environment I operate in, where risks and outcomes are the main variables to take into consideration; I can easily justify my choice when a good looking CV doesn’t work out, it’s harder when a non-traditional CV doesn’t go well. So how do I create a coherent, believable, and effective strategy to build a diverse, creative, smart and effective team without the constraints of traditional hiring methods? Can we embed experimenting with different profiles in the hiring process by taking a calculated risk in the expected business outcomes?

Enjoy the random walk!

Inferring causal impact using Bayesian structural time-series models

Whenever you are trying to predict the effect of a marketing campaign or population and you can’t AB test it, the traditional approach is to reach for a classic Difference-in-Differences scheme; those calculate the effect of a treatment on an outcome by simply comparing the average change over time in the outcome variable for the treatment group, compared to the average change over time for the control group. This Google Research paper demonstrates an alternative method based on state-space models. Such models make it possible to incorporate empirical priors on the parameters in a fully Bayesian treatment and accommodate multiple sources of variation, including the time-varying influence of contemporaneous covariates.

The End of Average: How We Succeed in a World That Values Sameness

This is the book that excited me the most this week and took a lot of my reading time. It really did speak to me. It highlights how our entire social system has been built around this average-size-fits-all model. Schools are designed for the average student. Healthcare is designed for the average patient. Employers try to fill average job descriptions with employees on an average career trajectory. The first half of the book is about explaining how this average-centric thinking came into place, the second half presents some strategies to tackle this problem.

The expected value of your impact on the world is like a vector. It is defined by two things: direction and magnitude.
