A friend of mine from a farming family in Europe once told me a story that his family would wait until the year one of his siblings was due to go to college and then invest in new farm machinery. Their reported net income for the year would reduce or go negative and the sibling would get to college effectively for free on a hardship tuition grant.

> The following histograms of Russian elections across polling stations shows curious spikes in turnout and results at nice, round, numbers (e.g., 95%) starting around 2004. This appears to indicate that there's election fraud via fabricated results

Two observations: 1. Why from 2004? Things were much worse in Russia before 2004. 2. The numbers of this election seem to agree with approval rating polls conducted by western agencies.

Haha, I recall seeing a similar plot with a "suspicious discontinuity" when I looked up data on home appraisal price vs sale price. I remember asking the loan officer why the contract was forwarded to the appraiser before they did the appraisal, because that might bias their assessment. She gave me a funny look and replied "that's kind of the point."

By 2004, a former KGB spook was in power long enough to introduce a falsification system.

The 1990s were worse economically in Russia, but Yeltsin was a relatively liberal politician and possibly didn't want to falsify elections.

Yep very common tactic for small business owning families.

Similar to car prices, we see the same mental rounding effect in rents. People will rent a home for $2100 or $2200, sometimes even $2150 for those truly dedicated to price finding, but hardly anyone rents an apartment for $2137.
