  1. I think the cups of coffee are tracking GDP per Capita, in econ class we got the same conclusion as here:

    “On the other hand, countries like Mexico, Costa Rica, and Israel are among the happiest, but their coffee consumption is relatively modest.”

    Just switch coffee consumption by GDP per C. Also, I think happiness in Israel is changing because of the war and these metrics are pre-palestinian modern war.

    This is a good GDP per capita proxy, I wonder what happens when you see the “cups per day” metric of countries with shady numbers like China, maybe that metric is more accurate, although you might need to include Tea as well.

    Also, this is a clear correlation with GDP per Capita but I will love to see the countries where it diverges. Also, in any way GDP per capita measures consumption or the availability of things to consume by people and coffee is one of them so that’s why I think they are very correlated, specially because coffee is not essential and universally liked so it measures when consumption goes above essentials.

  2. Seems like this is correlation but not causation. People are happier in wealthier countries. People who are wealthier can afford coffee. Correspondingly, coffee correlates with happiness.

  3. In Hong Kong, I see coffee consumption has a direct correlation with the economy. Also people are generally happier when the economy is growing. I tend to agree the correlation between coffee consumption and happiness.

  4. Brilliant. Finally some valuable research that we can apply to everyday life.
    A couple of related hypotheses that I wish someone would pursue:
    1. Human labor exists as a means to use and propagate coffee bushes.
    2. Like every plant that develops means of protection and reproduction, the coffee plant evolved a group of compounds that higher primates found highly satisfying, thus stimulating a technical culture that would ensure the long term growth and use of coffee.

  5. Giving up caffeine has made me a much happier, healthier and an at peace person.

    Coffee = wealth = happiness.

  6. “Ain’t no point getting out of bed if you ain’t living the dream/like making a pot of coffee when you ain’t got no cream”

    The oft-heard sociological comment *correlation does not equal causation* is used far too often, but this is one case where it clearly applies.

    A nice cold can of Monster energy has a 100% correlation with happiness for me…
