I'm going to sound cynical here so if you don't want to be confronted with negative content, please skip this one...

Did I just read an ad for "Mike's Hard Lemonade co." and Brand Studio Inc.? The "experiment" they made is not scientific and it doesn't have to exist to begin with. The point about happiness and media consumption was already researched seriously (which is also mentioned in this article).
So why does this article have to have a bright yellow background and spinning lemonades on the side and mentions a specific brand multiple times? Is it relevant to the "Good News Effect" or media consumption patterns? No... it's an ad that uses scientific work and the topic of happiness to boost a brand's public perception. Again... maybe it's just me... but having a discussion about happiness and media consumption should not be based on a Mike's Hard ad campaign imo.
