Invisible Women: Data Bias in a World Designed for Men

by Caroline Criado Perez

Sociology/Feminism

TL;DR

Basically, this book spills the tea on how most of the data used to build and run the world is based on dudes, making everything from your phone size to public toilets low-key hostile or dangerous for women. It's about spotting the 'gender data gap' – where data on women is missing or ignored – and understanding how this systemic bias leads to real-world problems in design, healthcare, work, and safety. The core methods are about recognizing the 'default male' thinking, identifying 'data gaps', and pushing for 'gendered innovation' to build a world that actually works for everyone, not just half the population. It's a wake-up call to see how data bias isn't just stats; it's literally shaping your life.

Key Chapter

Chapter - The Default Male: Why Everything's Built for Dudes

Okay, so this chapter is high-key eye-opening. It breaks down how so much data used to design literally everything – from phones to city infrastructure – is based on the 'average' human, but that 'average' is secretly just a man. It shows how this default male thinking means products are often awkward, inefficient, or even dangerous if you're not a dude. It's not just annoying; it's a systemic issue that makes daily life harder and less safe for women because their bodies, habits, and needs weren't considered in the basic data collection. Understanding this bias is key to seeing why the world feels low-key hostile sometimes.

Key Methods and Approaches

The Default Male

(AKA: 'Society's Basic Bro Data Model')

Description:

Identifying how data collection often uses male as the standard human, ignoring female variations.

Explanation:

Imagine trying to design clothes for everyone but only measuring guys. You're gonna end up with a lot of ill-fitting shit. This is like that, but with data for everything. Society just kinda defaulted to 'male' as the basic human model for collecting info, which means anything designed using that data is gonna be whack for anyone who isn't that default dude. It's the 'Oops, forgot about women' method of data collection.

Examples:
  • Crash test dummies being sized for average men, making cars less safe for women.

  • Medical research often using male subjects, leading to misdiagnosis or incorrect dosages for women.

  • Office temperatures set based on male metabolic rates, leaving women freezing their asses off.
