Withdrawal of endorsements/testimonials and apologies to my readers: I owe my readers an apology for endorsing a man based on limited information. I have known Dobelli for a while and never read him as his work was in German. I was under the impression that he was writing a book on cognitive biases from a novelist's point of view... I trusted what he said I gave him an endorsement thinking he would do a good job as a novelist (I was careful to endorse the person, not the book). I also introduced him to my agent and pushed for his book to be published. But I was completely shocked when, after I got a copy of the book at his New York book party, I opened the English version of the book. I saw passages from my work transcribed, examples rapidly copied, with small modifications... not a novelist's approach. Sadly, it took a decade to discover the nature of a man whose works I had never read.
