TLDR: This article is not an article but an ad for Belong. Don't waste your time.

Here is a trick about generational cohorts: they are complete non sense whose sole reason of being is allowing sociology majors to write uninteresting papers and newspapers to fill in their columns for cheap.

If you need convincing, let's do a little thought experiment. Let's define new cohorts by puting the borders exactly in the middle of the current one. Do you think you could do exactly the same studies and write basically the same papers with only little variation in results?

Once you realise the sampling doesn't matter, you can look at the articles critically. Notice that here for exemple there is zero actual data provided. It's all very handwavy "some young people", according to "a senior lecturer in finance" in a random college, etc, etc. Basically all fluff.

Then, you might wonder but why is a publication actually wasting space on this tosh then? Well, because it's an ad obvioulsy: "Making a transaction more visceral and difficult can make people think twice about doom spending, Samantha Rosenberg, co-founder and COO of Belong, a wealth-building platform"
