that weighed seven tons. I can’t read the articles in the paper. I don’t know what they mean. I don’t know what kind of a machine it was just because it weighed seven tons. And there are now sixty-two kinds of particles, and I would like to know what atomic bullet he is referring to.
This whole business of statistical sampling and the determining of the properties of people by this manner is a very serious business altogether. It’s coming into its own, but it’s used very often, and we have to be very, very careful with it. It’s used for choice of personnel—by giving examinations to people—marriage counseling, and things of this kind. It’s used to determine whether people get into college, in a way that I am not in favor of, but I will leave my arguments on this. I will address them to the people who decide who gets into Caltech. And after I have had my arguments, I will come back and tell you something about it. But this has one serious feature, among others, aside from the difficulties of sampling. There is a tendency, then, to use only what can be measured as a criterion. That is, the spirit of the man, the way he feels toward things, may be difficult to measure. There is some tendency to have interviews and to try to correct this. So much the better. But it’s easier to have more examinations and not have to waste the time with the interviews, and the result is that only those things which can be measured, actually which they think they can measure, are what count, and a lot of good things are left out, a lot of good guys are missed. So it’s a dangerous business and has to be very carefully checked. The things like marriage questions, “How are you getting along with your husband,” and so on, that appear in magazines are all nonsense. They go something like this: “This has been tested on a thousand couples.” And then you can tell how they answered and how you answered and tell if you are happily married. What you do is the following. You make up a bunch of questions, like “Do you give him breakfast in bed?” and so on and so on. And then you give this questionnaire to a thousand people. And you have an independent way of telling whether they are happily married, like asking them, or something. But never mind. It doesn’t make any difference what it is, even if the test is perfect. That’s not the part where the trouble is. Then you do the following. You see about all the ones who are happy—how did they answer about the breakfast in bed, how did they answer about this, how did they answer about that? You see it’s exactly the same as my rat race, with right and left. They have decided on the odds of the thing in terms of the one sample. What they ought to do to be honest is to take the same test that has now been designed, in which they know how to make the score. They’ve decided this gets five points, that gets ten points, in such a way that the thousand that they tried it on get marvelous scores if they are happy and lousy scores if they’re not. But now is the test of the test. They cannot use the sample which determined the scoring for them. That’s going backwards. They must take the test to another thousand people, independently, and run it out to see whether the happy ones are the ones that score high, or not. They do not do that, because it’s too much trouble, A, and the few times that they tried it, B, it showed that the test was no good.
Now, looking at the troubles that we have with all the unscientific and peculiar things in the world, there are a number of them which cannot be associated with difficulties in how to think, I think, but are just due to some lack of information. In particular, there are believers in astrology, of which, no doubt, there are a number here. Astrologists say that there are days when it’s better to go to the dentist than other days. There are days when it’s better to fly in an airplane, for you, if you are born on such a day and such and such an hour. And its all calculated by very careful rules in terms of the position of the stars. If it were true it would be very interesting. Insurance people would be very interested to change the insurance rates on people if they follow the astrological rules, because they have a better chance when they are in the airplane. Tests to determine whether people who go on the day that they are not supposed to go are worse off or not have never been made by the astrologers. The question of whether it’s a good day for business or a bad day for business has never been established. Now what of it?
Maybe it’s still true, yes. On the other hand, there’s an awful lot of information that indicates that it isn’t true. Because we have a lot of knowledge about how things work, what people are, what the world is, what those stars are, what the planets are that you are looking at, what makes them go around more or less, where they’re going to be in the next 2000 years is completely known. They don’t have to look up to find out where it is. And furthermore, if you look very carefully at the different astrologers they don’t agree with each other, so what are you going to do? Disbelieve it. There’s no evidence at all for it. It’s pure nonsense. The only way you can believe it is to have a general lack of information about the stars and the world and what the rest of the things look like. If such a phenomenon existed it would be most remarkable, in the face of all the other phenomena that exist, and unless someone can demonstrate it to you with a real experiment, with a real test, took people who believe and people who didn’t believe and made a test, and so on, then there’s no point in listening to them. Tests of this kind, incidentally, have been made in the early days of science. It’s rather interesting. I found out that in the early days, like in the time when they were discovering oxygen and so on, people made such experimental attempts to find out, for example, whether missionaries—it sounds silly; it only sounds silly because you’re afraid to test it—whether good people like missionaries who pray and so on were less likely to be in a shipwreck than others. And so when missionaries were going to far countries, they checked in the shipwrecks whether the missionaries were less likely to drown than other people. And it turned out that there was no difference. So lots of people don’t believe that it makes any difference.
There are, if you turn on the radio—I don’t know how it is up here; it must be the same—in California you hear all kinds of faith healers. I’ve seen them on television. It’s another one of those things that it exhausts me to try to explain why it’s rather a ridiculous proposition. There is, in fact, an entire religion that’s respectable, so called, that’s called Christian Science, that’s based on the idea of faith healing. If it were true, it could be established, not by the anecdotes of a few people but by the careful checks, by the technically good clinical methods which are used on any other way of curing diseases. If you believe in faith healing, you have a tendency to avoid other ways of getting healed. It takes you a little longer to get to the doctor, possibly. Some people believe it strongly enough that it takes them longer to get to the doctor. It’s possible that the faith healing isn’t so good. It’s possible—we are not sure—that it isn’t. And its therefore possible that there is some danger in believing in faith healing, that its not a triviality, not like astrology wherein it doesn’t make a lot of difference. It’s just inconvenient for the people who believe in it that they have to do things on certain days. It may be, and I would like to know—it should be investigated—everybody has a right to know—whether more people have been hurt or helped by believing in Christ’s ability to heal; whether there is more healing or harming by such a thing. It’s possible either way. It should be investigated. It shouldn’t be left lying for people to believe in without an investigation.
Not only are there faith healers on the radio, there are also radio religion people who use the Bible to predict all kinds of phenomena that are going to happen. I listened intrigued to a man who in a dream visited God and received all kinds of special information for his congregation, etc. Well, this unscientific age… But I don’t know what to do with that one. I don’t know what rule of reasoning to use to show right away that it’s nutty. I think it just belongs to a general lack of understanding of how complicated the world is and how elaborate and how unlikely it would be that such a thing would work.
But I can’t disprove, of course, without investigating more carefully. Maybe one way would be always to ask them how do they know it’s true and to remember maybe that they are wrong. Just remember that much anyway, because you may keep yourself from sending in too much money
There are also, of course, in the world a number of phenomena that you cannot beat that are just the result of a general stupidity. And we all do stupid things, and we know some people do more than others, but there is no use in trying to check who does the most. There is some attempt to protect this by government regulation, to protect this stupidity, but it doesn’t work a hundred percent.
For example, I went on a visit to one of the desert sites to buy land. You know they sell land, these promoters—there’s a new city going to be built. It’s exciting. It’s marvelous. You must go. Just imagine yourself in a desert with nothing but some flags poked here in the ground with numbers on them and street signs with names. And so you drive in the car across the desert to find the fourth street and so on to get to the lot 369, which is the one for you, you’re thinking. And you stand there kicking sand in this thing discussing with the salesman why it’s advantageous to have a corner lot and how the driveway will be good because it will be easier to get into from that side. Worse, believe it or not, you find yourself discussing the beach club, which is going to be on that sea, what the rules of membership are and how many friends you’re allowed to bring. I swear, I got into that condition.
So when the time comes to buy the land, it turns out that the state has made an attempt to help you. So they have a description of this particular thing that you have read, and the man who sells you the land says it’s the law, we have to give you this to read. They give it to you to read, and it says that this is very much like many other real estate deals in the state of California and so on and so on and so on. And among other things, I read that although they say that they want to have fifty thousand people at this site, there is not water enough for a number
