The graphic presentation lends itself to misinterpretation. For example, the article states that "Somewhat surprisingly, only 14% of poll participants think high-yield bonds are over-inflated." Actually, 54% thought so. That is, one must account for those who thought only high-yield bonds were in a bubble (14%), plus the "A and B" responses (5%), plus the "A and C" group (5%), plus those who thought all categories were in a bubble (30%).
