DESCRIPTION
What you thought was a 7/10 ‘average’ movie is really a 5/10.
What you thought was a 7/10 ‘average’ movie is really a 5/10.A Chrome extension that shows a normalized IMDB rating next to the official one, correcting for human rating biases.
## Motivation
People rarely use the full 1–10 scale.
- Loss aversion makes low scores feel stronger than high ones, so ratings cluster around 7–8, leaving 5 underused.
- Most users treat 7/10 as “average” and 8/10 as “good,” skewing the mean to 7–8 instead of 5.5.## Features
- Instant display of the normalized rating (1.0–10.0) on each movie page.
- Vote-count filter: applies only to titles with at least 500 votes for accuracy.
## Normalization Algorithm
Uses a probability-integral transform followed by an inverse-normal mapping to recenter ratings at 5.5.
