Inspired by this tweet, researcher Kate Petrova did a deep dive of scented candle reviews before and after the pandemic. Surprisingly or unsurprisingly, reviews of scented candles took a deep drop after the pandemic started with numerous complaints that the candles lacked any scent. One of the symptoms of COVID-19 is losing your sense of smell and taste so, ya know, put two and two together.

First, I downloaded a random subsample of US-based customer reviews of the 3 most popular scented candles on Amazon. Between January 2017 and January 2020, the average rating stayed around 4.3/5, but there was a sharp drop between January and November 2020. 2/n pic.twitter.com/kpCRZ1StKZ

Since the beginning of 2020, customer satisfaction with scented candles has been dropping at a much faster rate compared to unscented candles. 4/n pic.twitter.com/LULlUh9P6W

You can view the complete Twitter thread here. Personally, I’ve noticed my candles have also started losing their flavor. Not sure what gives, but they taste terrible now.
