What Yesterday, The Beatles' song, is really about

It isn’t a love song. It is about Paul McCartney's mother's death.

I found out from the horse’s mouth, so to speak, from this interview with Paul McCartney airing on NPR this week, in honour of the 50th anniversary of The Beatles’ conquest of America.

In the interview, Paul talks about how he lost his mother as a teenager. John Lennon also lost his mother at about the same age, and that shared experience of loss was a deep bond John and Paul shared. However, as working class lads from the North, they couldn’t talk about it. It just wasn’t done. It was put to Paul much later in life that Yesterday might be about his feelings when his mother died, and it dawned on Paul that that was probably true.

The song sounds different now, now that I know this interpretation. Still a great song. But different.

Satya Nadella: The Rorschach Ink Blot CEO

Satya Nadella, Microsoft CEO

Since Satya Nadella’s appointment as Microsoft's CEO, my Facebook news feed and email inbox have been chock-a-block with stories about what Mr Nadella's success means.

Some think Satya Nadella’s success is a triumph for “Indian values, like empathy, patience and humility”. Others think it is “a slap in the face for the Indian system” (because Mr Nadella felt the need to emigrate to the USA); that it reflects the “failure of the IITs” (because such a prestigious tech job went to a guy from lowly Manipal University); that it is a triumph for the game of cricket  (because Satya learnt about leadership and teamwork as a cricket playing schoolboy in Hyderabad); that it reflects the greatness of Amercia (because you don’t have to be Bill Gates’ son to become CEO of Microsoft); that it reflects the failure of America (because homegrown talent lags so far behind educated, motivated immigrants); that it reflects the skills Mr. Nadella learnt at his family dinner table (his father was a senior IAS officer who served on India’s Planning Commission); etc. etc.

All these interpretations are have some basis in fact. But having absorbed all these interpretations, my conclusion is that Satya Nadella's success is a contemporary Rorschach Ink Blot test. Any observer’s interpretation tells you a lot about the observer's state of mind. It tells you little or nothing about the meaning of Mr Nadella’s success, because Mr. Nadella’s success doesn’t actually mean anything, beyond the very specific context of Microsoft’s executive team.

The human brain is amazingly good at seeing patterns, even when there aren’t any patterns to see.
