If you're saying something that people don't want to hear or accept, a significant proportion of them will reply with hostility. Not because they know the facts, or because they have researched it themselves, but because they're so psychologically involved in believing good news that they will oppose it with a reflex.

The market is incredibly inefficient and capable on rare occasions of being utterly dysfunctional. And people have a really hard time getting their brain around that fact. They want to believe that it's approximately efficient almost all the time, and it simply isn't true.

By background I'm both a Quaker and a Yorkshireman, which I like to call double jeopardy.

I find the parallels between how some investors refuse to recognise the trends and our reaction to some of our environmental challenges very powerful. There is an unwillingness to process unpleasant data.

One day we will have more inflation, and our bonds will bleed like a pig. The only reason for buying long bonds is short-term or as a desperate haven for terrorized investors. But the potential to make longer-term real money is naught.
