Would you still believe that the probability of heads is 0.5?<\/p>\n<p>The point: some people only trust experience, when they have it. Experience may not necessarily be direct, but rather based on someone else&#8217;s they know, or even a synthesis of indirect experiences. <em>If I can reach Person X, they&#8217;ll know what to do &#8212; they&#8217;ve never failed me.<\/em> Even in a completely new situation, they will trust Person X, given how helpful they&#8217;ve been in other situations.<\/p>\n<p>How people compute probabilities &#8211; even being totally unaware they&#8217;re doing so &#8211; can make one&#8217;s choices different from another&#8217;s. You see the choices, but the decision process behind them can be very subtle.<\/p>\n<p>With the world changing so quickly, it can be harder and harder to trust reasoning, or &#8220;theoretical&#8221; probability, since the factors involved constantly change. I would have said oil at a negative price was impossible, but it happened. More and more impossible things seem to happen; perhaps as a result, I sense that many people are becoming even less theoretical in how they determine probabilities, even with so much more information seemingly available.<\/p>\n<p>Source:<\/p>\n<p><a href=\"https:\/\/www.marketwatch.com\/story\/oil-prices-went-negative-a-year-ago-heres-what-traders-have-learned-since-11618863839#:~:text=On%20April%2020%2C%202020%2C%20the,the%20New%20York%20Mercantile%20Exchange.\">marketwatch.com<\/p>\nJack of <a href=\"https:\/\/www.oracletutoring.ca\">Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.\n","protected":false},"excerpt":{"rendered":"<p>Self-tutoring about probability: the tutor gets (perhaps) philosophical as well.
