How every book works
Every claim carries a label
Each piece of advice is graded by how strong the research behind it is, on the day it was last reviewed. You always know what is settled and what is still open.
- Strong evidence “A watch ECG cannot detect a heart attack or a stroke.” Is My Wearable Lying to Me?, Chapter 5
- Moderate evidence “Devices are poor at recognizing when you're awake, so they tend to overestimate sleep.” Is My Wearable Lying to Me?, Chapter 8
- Debated “Whether skin tone affects wrist heart rate is still unsettled.” Is My Wearable Lying to Me?, Chapter 2
- Unproven “Raising the HRV number on your device makes you healthier.” Is My Wearable Lying to Me?, Chapter 9
