[i]Sits at desk with a face down picture[/i] "I am going to show you a drawing of a circle." [i]Flips over paper to reveal a drawing of a square[/i] "What do you see? Did the fact that you were expecting to see a circle make this image appear to be round?" "Now I am going to show you a circle that is so big that you can't see the whole thing at once." [i]Shows tiny segment line drawing with a slight curve, that, if completed, would create a circle one hundred miles in circumference [/i] "Can you tell if this segment is a straight line or a curve? I'll provide tools and equations in order for you to examine and calculate whether this segment is a straight line or has curvature." [i]Repeats exercise with ever-increasing circles, sometimes stating that a square will be revealed, sometimes stating that a circle will be revealed, each tine making available everything needed to verify if the statement is congruent with the image [/i] Summary: Not believing everything you are told, and verifying facts for yourself = good for you. That's awesome. Having tools and equations that are scalable, being able to test and measure data, and then refusing to believe the data to be true because you have already made up your mind = biased and inaccurate conclusions. So believe what you want based on the data you collect, or just follow what you're told and be blissfully ignorant. There are plenty of people who believe the earth is round based on only what others tell them and show them without going to the lengths of measuring, calculating, and deducing for themselves. So flat earthers, I applaud your efforts, and agree with the sentiment that you should not readily accept what you're told as fact without evidence. But the Earth. Is. Round. It doesn't merely [i]look[/i] round because we are presupposed to that perception. Below I am going to provide 4 lines, equal length, connected to make a squiggly shape, two points at the bottom that connect the right and left pairs, with one point in the middle to connect the middle pair: L Does your presupposition of my description of that character make it look as if I typed a W? Or does it look more like two lines connected at one point to form a right angle? People can see what they want to see, sure. But too many people go too far and assert they see a W when they are really looking at an L.
