To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Your Brain on Nature was well written and had loads of cases and data on the role of nature in our health. However, the data were largely correlative - I.e. the results of correlating health outcomes with everything from potted plants to views of trees in a hospital room. I was looking for causation more than correlation which is why I was intrigued by the title that mentioned the brain. But there wasn't much on the brain, possibly because not enough is known yet. The data on health and nature were useful though and I look forward to seeing more on the agency of the correlations, the brain.
