It is hot. Very hot. And we are only a few weeks into summer.

 When we think about how hot it is, we tend to think about the air temperature, because that's what we experience in our daily lives.

But most of the heat stored near the surface of the Earth is not in the atmosphere, but in the oceans. And we've been seeing some record ocean temperatures this spring and summer.

Cognitive blind spots

Bild
Cognitive blind spots are undermining our ability to see the world as it is, rather than as we would like it to be. At the start of the 21st century, western elites generally assumed that globalisation, democracy and the free market were self-evidently good, and would keep spreading, creating peace. N o longer.  FIS, Swiss Federal Intelligence Service, has published a manual about cognitive blind spots. 18 different cognitive biases that hamper our thinking, such as “group think” (adhering to the cosy assumptions of our tribe), “anchoring” (relying exclusively on whatever information we see first, say on social media),  “confirmation bias” (only seeing data that reinforces pre-existing views),  “mirror imaging” (assuming others think like us),  “absence of evidence” bias (failing to think about the data we lack)  and “survivorship bias” (judging data only with success stories, not failures).

Martin Wolf; The next crash - Why this time might not be different

Stock markets are not only ignoring the obvious threats, but seem imbued with extreme optimism. In the autumn of 1929, Irving Fisher, one of the greatest American economists, stated: “Stock prices have reached what looks like a permanently high plateau.”  This turned out to be one of the most incorrect forecasts ever made: in short order, US and global stock markets were hit by the Great Crash, which was followed by the Great Depression. Maybe markets were in some sense “right” before the crash and wrong after it. But who cared? For investors and the hundreds of millions of people across the world whose lives were upended by the disaster, the gods of the stock market had failed for a generation. Why might this story be relevant today? The answer is that the valuation of US stocks is even higher today than in September 1929.  The first global financial crisis after the disaster of the 1930s in 2007-09: the easy monetary — and relaxed regulatory — policies adopted after the stoc...
