The ratio of brain weight to body weight is a better indicator of intelligence because it takes into account the fact that larger animals will naturally have bigger brains but that doesn't necessarily mean they are more intelligent. The more accurate metric is the ratio of brain weight to body weight, which allows us to compare animals of different sizes.
