<p>First, the article you read was written (in bulk) over 40 years ago, when Caltech was quite a different institution (over 30% failed out, compared with fewer than 10% today). And, for what it's worth, I'm a living, breathing Caltech student, and my passion for math and science has only increased as a result of being here. And I'm not unique in this respect. At all. By the way, to say that the experience of learning science here is "passive" or "external" seems totally inconsistent with the experience I have been through. With the abundance of research and the availability of the faculty to bat around ideas about the material, it is anything but passive.</p>
<p>Nevertheless, if you are ambivalent to begin with about how much you love science, Caltech is likely to be a bad bet. For the few (the proud...) who really love science immensely AND have sufficient ability and perseverance, Caltech will educate you like no other place can. For those who love science but lack sufficient ability or perseverance, Caltech is likely to be quite painful. If you think you might be in the latter category, it's safer to go somewhere else.</p>
<p>This ties into the reason Caltech loses some admits to more mainstream schools with broader programs. Simply put, not everyone is cut out to take what we have to offer. The intensity and focus of this experience appeals only to the most confident and the most committed. In this sense, there are two sorting processes that determine who ends up at Caltech. In the first process, it is decided whether you are the kind of person who can get in. In the second process, you decide whether you are the kind of person who would want to go. People who don't have the gung-ho-ness to jump at Caltech are probably safer at softer places.</p>
<p>In fact, it would be a strange world in which Caltech would be more appealing "on average" than Stanford. The latter is safe, diverse, and fairly easy. The former is focused and very very hard. It's no surprise that many people shy away.</p>
<p>Perhaps you have discerned that Caltech (like Rolex or Bentley) does not aim to sell to the average consumer of education. We aim to sell to a very special and rare kind of consumer who values our good. Whereas a fairly huge variety of undergrads could be happy at Stanford, only a select few (outliers on a few dimensions) would be very happy at Caltech. You have to decide whether it's right for you.</p>
<p>So, in short, I'd say -- don't feel bad if Caltech seems like it might be too hard, or too much work, or too focused. For the vast majority of applicants to top-10 schools, it is those things exactly. If you are unaverage in exactly the right kinds of ways -- only then should you consider coming here. And if you're not sure, don't.</p>
