Cold Reading

Posted by on Mar 6, 2012 in critical thinking | Comments Off

So a few years ago Victoria found an old receipt in a box. She calls to me, on the other side of the room, and says, “Hey Michael, guess what the date is on this receipt.”
Without so much as a second of hesitation I responded, “2000”.
She was stunned, “How’d you do that?”
“I’m psychic.” And I raised my eyebrows.

Now if that’s all the description I’d given of the event it might seem a little mysterious. But I assure you there was nothing mysterious about it at all. Victoria had actually told me the year a few minutes earlier and she didn’t even realize it. Making it seem really spooky when I repeated it back to her.

This is process that so-called psychic use all the time. It’s called cold reading. They take information from their “mark” a turn the information back on them. When done well it appears that the person claiming to have paranormal powers has actually provided information to you that they couldn’t have known otherwise. Typically they ask a series of questions. Based on their mark’s responses they will fine tune the questions until they can then make a very high probability guess. The real art is to make the mark forget the string of questions, especially all the wrong answers, and focus entirely on the final high probability guess.

Sometimes the psychic will base their first question on a non-verbal detail. If the mark is anywhere outside normal appearance (taller, shorter, thinner, fatter than average) they might start with something obvious like “Were you teased a lot as a teenager?” Then, no matter how you answer, they will build on that to fine tune their final “prediction”. They ask vague questions, expect their mark to narrow them down and forget all the wrong answers. My point here is that they really aren’t telling them anything at all. The mark is providing the answers, not the so-called psychic.

I had a recent experience with a very bad cold-reader. He told several personal stories and expected me to relate to his stories and add details so he could build upon them for his final “prediction”. He would make vague statements and expect me to clarify so he could build on them. In a sense I just turned the tables on him. When he would try to get me to fill in details I would just ask him follow up questions to his story. In the end I think he got rather frustrated with me. I wasn’t trying to be difficult. I just recognized his strategies and did my best not to fall for them.

The sad part is that I honestly don’t think that the guy I was talking to even knew what he was doing. I don’t think he was consciously trying to deceive me. But he was trying to get me to reveal information so he could claim that it was something that he sensed, or suspected all along.

Now back to my receipt story, Here’s the story again with supporting detail and in the full context:
A few years ago we did some remodeling to the house. We stashed a bunch of stuff in shoe boxes to sort through and clean out later. A year or so had passed an Victoria and I were decluttering. We were sitting on the floor each going through shoe boxes of papers. I happened to have a shoebox with mostly stuff from the 90s in it. I remember noticing how so much of the clutter in my box was from the same couple of years. Victoria found some old bank account information form when we opened an account for Noah. She told me about it and laughed at some of the information on the paperwork. Noah was born in 2000 and we opened the account the year he was born because he had an income. Victoria was doing market research on diapers and the checks came payable to Noah.

So half an hour later I was still sorting my papers from the 90s and I assumed that she was still on the same box too. So when she asked me to guess the date I just said, “2000”. It was vague, I didn’t give a month or a day, and I had a pretty good chance of being right. And even if I had been wrong she’d have never thought about it again.

“It’s kind of sad that just paying attention to the little details in people’s lives gets mistaken for a paranormal power.”

Humility

Posted by on Feb 28, 2012 in critical thinking, debate, LDS Church, science | Comments Off

I’m going to do my best to get back to blogging more frequently. I really enjoy it. It helps me organize my thoughts. Considering the topic of my last couple posts I took a self-imposed hiatus. I guess I was just being kinda timid about how people would respond. But after several long talks with my lovely bride she has convinced me that I need to get back in the swing of blogging again. So here it goes.

I have a meeting scheduled with the Stake President tomorrow. I haven’t attended church for almost 6 months now, except for one for the primary program because I had kids participating. This is about the fifth time that he has tried to meet with me but previously he’s cancelled at the last minute. I’m not pretending that I don’t know what he wants to talk about. In preparation for our discussion I’ve been reading my previous blog posts and talking things out with friends and family.

This is his meeting. He called it and I’m not planning on hijacking it. However, I am more than aware of the Taylor gene that makes me come across as confrontational when I really don’t mean to be. My goal is to just give him honest answers to his questions. If time permits and depending on that mood I may ask a few of my own, but those are of secondary importance to me. I have no desire at all to have anybody change their mind just because I have lost my believe in the LDS church. My only goal in agreeing to meet with him is shared understanding. I recognize that his goal will likely be more than that and I’m open-minded to new answers. Just because a decade of questioning has not provided any new answers so far I’m not closing the door to the possibility.


I’ve really enjoyed the access that the internet has given me to videos and podcast of some of the most brilliant scientists, philosophers and educators in the world. I am particularly amazed at how most of them deal with people that they disagree. Far from the insults and cut-downs they have shown me that it is possible to vehemently disagree but still be polite, respectful and cordial in that disagreement. I admire this. It’s a trait I am consciously working on developing. The following clip is one of my favorite that illustrates this type of civil disagreement that is all too frequently absent in other aspects of life. Incidentally I am in complete agreement with Ann Druyan on her appraisal of the lack of humility in the religious world today.

The King Swing

Posted by on Oct 4, 2011 in climbing, critical thinking, family, introspection, LDS Church, life lessons, religion | Comments Off

(Warning!! This post is of a very personal nature and may offend some readers.)
This is a video from a very popular rock climbing route in Yosemite. This technique is called a pendulum traverse. Climbers call it "The King Swing” and it takes place on a route called “The Nose” on the 3000’ feature called El Capitan. About halfway up this particular route the cracks and features kind of peter out once you get to the top of that flake the photographer is standing on. Since the rock doesn’t have any little cracks or bumps there is subsequently nothing to pull up on or stand on. Therefore, no way to climb it. The only solution is to go back down and see if you can find another path. Sometimes you see another path but there really isn’t any way to get to it from underneath. The only feasible solution is to do a pendulum traverse. Just as the name implies you lower down as far as you have to and swing back and forth until you can grab a section of rock that is will allow you to climb it.

I’ve done several pendulum traverses, although not this one. They can be quite intimidating. Sometimes you’re not quite sure if you’re swinging into a section that will be just as unclimbable as where you were. One time it was an emergency situation and this was the safest technique to get off the rock during a thunderstorm. But every time I was more than a little apprehensive. The technique requires much more planning than it appears and things have to be done just right in order to stay safe.

Even though the route ahead seems insurmountable it’s quite a weird feeling to hang your butt on the end of a rope and run back and forth hoping to grasp something better, something that will allow you to keep progressing. It’s not exactly the safest thing to do. The times I’ve done them were only in situations where I was absolutely sure that it was the only way to keep on progressing. The risks can be high, but the rewards can be even greater if this leads you to better climbing or a way out of the current predicament.

I’m at a point in my life where I need to take the King Swing. I’ve been on a path that has provided me with much joy and happiness up to this point. I felt like I was growing, learning and progressing. But for the last several years I’ve been stuck on a ledge looking for ways to keep moving up and not finding anything to hang on to. It has taken me quite a while to even consider looking for another path. I’d been raised to believe that the path I was on was perfect and there was no reason to stray from it. But I just couldn’t see where or how to continue. Consequently, I’ve lowered down a little bit and begun to swing back and forth looking for another path.

I believe I’ve found a path. I’m not quite sure how good the climbing will be over there but I’m sure it is more promising than where I am now. Who knows? This new path may lead me back onto my original path from a different angle. Or I may end up having to lower back down this new route too and look for yet another path. I just don’t know right now.

To those of you who aren’t having any problems negotiating the blank sections of the original route, I have no criticism at all. Congratulations. You are better skilled at finding the route than I am. Simply because I am looking for a different path I have no criticism at all if you are making it work for you.

I’m not suggesting that anybody take the steps that I about to without doing at least as much thorough research, soul-searching and earnestly looking for all of the answers. This decision, to take the swing, has not be reached casually. In my case it has been years and years of agonizing study and prayer that has brought me to when I am now.

It’s time to set the metaphor aside. This post has nothing to do with rock climbing. I’m talking about my membership in The Church of Jesus Christ of Latter-Day Saints. For the past several years I’ve been stuck on a ledge and could find no way to keep moving forward. I’ve discussed some of the specifics on this blog numerous times, but I don’t wish to get into them today. To my friends and family who are members of the church I hope that you will take this with the spirit with which it is intended. I am very grateful that you are in my life and I mean absolutely no disrespect to you at all. I have never felt that absolute agreement on everything was necessary for me to love you and this decision will not stop that. I hope that you can see it in your heart to still love me. The most apprehensive part of this decision has been the considering, reconsidering and re-reconsidering the effects it will have on my family.

I fully expect that many of you will not understand my decision. I’m under no delusion that this will be easy. But I believe it will be better in the long run. I’ve seen other friends and family members struggle with some of the same issues that I have. It’s been very selfish of me to let them struggle alone while I conceal my struggles and go through some of the same things they have been.

I am grateful for everything that I have learned so far on my path. Please don’t think that I am going to consider abandoning all of the progress and the good things that I’ve learned in the process. I have no plans to start stopping by liquor stores or breaking any other of the moral and ethical codes the church has taught me. Quite the opposite; I cherish those values and I look forward to continuing to incorporate them into my life.

The private answers to the questions I have asked in my prayers have led me in an unexpected direction, a spiritual path which, at least for now, has proven incompatible with Mormon doctrine. This search for a new route has brought me some of the most profound surprises and also the deepest sadness of my life. It is very hard for me to leave a path that I love so much. Read More

Conflicts

Posted by on Jun 23, 2011 in critical thinking, family, introspection, reason | Comments Off

Many years ago I played saxophone in my middle school band. I wasn’t very good at all. Typically I was either 3rd or 4th chair. That depended entirely on how many saxophones there were that semester, 3 or 4. In band if you wanted a promotion to a higher chair you had to “challenge” the chair in front of you. Friday’s were challenge days. We would go around the band and listen to each challenge. Typically the 2 players would each play the same piece and they were judged by the band director. If that challenger played it better they advanced to that chair. Sometimes challenges would be issued to show an expertise in a specific technique. I remember challenges issues entirely on breathing at the correct spots in a piece.

I will always remember one particular challenge. I was in the flute section. Our band director had been working with us on keeping our fingers close to the keys; basically not wasting energy and time by completely straightening your fingers when a smaller motion will get the job done. So the 3rd chair recognizes that she had an advantage in this area and challenges the 2nd chair to a piece. Here’s where it got interesting. She challenged him based on two criteria, accuracy and keeping fingers on the keys. Both musicians played the piece and then the director had to make a decision. The 3rd chair flutist clearly had mastered the concept of keeping her fingers near the keys. However the 2nd chair played the piece with more accuracy. So what do you do? Which of the 2 challenge criteria trumps the other? Without any ground rules in place before the challenge he decided that a tie meant no change in the positions.

No you’ve probably already realized that this post isn’t really about who sits where in a middle school band class. At our company we have a long standing safety creed. Until a few years ago it read,
“No job is so important and no service is so urgent that we can not take time to perform our work safely."
I have no problem with that at all. It’s simple and to the point. When I would get spot checked while on site my supervisor would ask me what it meant in my own words. I would typically say something like, “It’s just your phone or your internet. Nobody should have to get hurt to make this work.”
Well a few years ago we were bought out by a larger company. And that company made a slight change to the safety creed. It now reads,
“No job is so important and no service is so urgent that we can not take time to perform our work safely and in an environmentally responsible manner."
Hmmm. Now like our band director I am presented with a possible conflict. I have no problem with either of the goals expressed in this creed as long as they don’t conflict with each other. But what about when they do conflict? I can think of several cases where the most environmentally responsible thing to do would not be the safest thing to do in the short term. What if a coworker is being attacked by a Canada Goose? Whose side do I take? The coworker’s or the threatened migratory bird? While I have no criticism of either goal, I just think that bringing up environmental issues in the context of a safety creed waters down the creed and could actually make a situation more dangerous.
Now on to other issues. How many times do we find ourselves in situations like this? Do I swerve to miss the animal in the road and endanger my passengers in the process? Or make a professional decision without considering the family? I guess my only point is that you need to be clear which goal would trump the other before you get into that situation. Read More

Proofiness

Posted by on Mar 31, 2011 in books, critical thinking, politics | Comments Off

Years ago I my dad had a book laying around the house called How to Lie with Statistics. The book took the form of a how-to book. The entire premise being that people don’t really understand statistics or even math very well so it presented some tongue in cheek suggestions on how to spin your numbers to say something that they don’t really. The book was intended to be used as a defensive tool to teach the readers how to notice when somebody else is lying to them with numbers.

If How to Lie with Statistics was the 101 course then Proofiness: The Dark Arts of Mathematical Deception by Charles Seife is the masters level course. If you are uncomfortable with uncertainty you might want to avoid this book. Seife successfully shows that many of the numbers that control our lives are at best gross estimations and at worst deliberate fictions. Instead of saying "Hey there are a bunch of Communists in the Justice Department.” Joseph McCarthy knew that we would give more credence to a number so he made one up, 205. Where did he get that number? He just made it up. And people bought it. Seife shows that people tend to believe numbers even if there is no reasonable expectation that the number is even correct. This reminds me of the story of the surveyors who were measuring Mount Everest and found out that it was exactly 29,000’. The supervisors in charge altered the data because 29,000’ looked like and estimate so they added a few feet to the mountain and called it 29,029’.

Seife shows how pervasive our trust of numbers are in everyday life. Most people accept that 98.6F is the normal temperature for a human. Is this number really accurate to one decimal point? No it isn’t. The doctors who determined the average normal temperature for humans only claimed it was accurate to the decimal point in Celsius and even then it could vary by person. 37C is the normal temperature, but when you convert that to Fahrenheit you get a number that appears more accurate than the number you started with. The real average temperature for humans is somewhere between 36C and 38C or 97F to 100F but we really can’t be more accurate than that. Yet how many times have you assumed that you had a fever at 99.0F? Not to say you weren’t really sick, but you don’t need the artificially accurate number to tell you that. This is Proofiness.

Seife explains case by case how proofiness has been used to free the guilt; O.J. Simpson, execute the innocent, elect Presidents and Congressmen, justify military action, justify backing out of arms treaties, support just about every type of legislation on both sides of the aisle on issues ranging form abortion to gun control etc. etc. etc. The abuses of math in our society were very disheartening. Personally I think Seife had his own bias as to which side of the aisle was more guilty of proofiness than the other. That being said he was just as thorough in his rebuke of the right as he was the left.

Many parts of the book were quite depressing. The specific cases, especially those were lives were lost seriously caused me to question the motives of some of our elected official. However, overall I thought the book was an excellent primer on what to look for and what follow up questions to ask when you are given information, especially information that involves counting , math and statistics.

The whole time I was reading this book I keep thinking about this one joke. 5/4th of American’s have problems with fractions. Seife has convinced me that this number may even be higher. Read More
