I don't believe he's deliberately lying, though, any more than are the string theorists. Theoretical physicists are human, after all, and when you spend years building a respected academic reputation doing hard math that seems to hold even a shred of hope, it's hard to hear dissenting opinions. Your comments encourage me to read books or articles by his "opponents" after I read his.
Honestly, that is not the mindset that most actual scientists have. If you read interviews with them, or talk to them, you'll see they often say things like "and if it turns out we're wrong, that's even more interesting!" People become scientists because they feel a drive to search for answers and discover new secrets. They don't do it because they want to believe one thing and hold onto it and refuse to listen despite any evidence against them. Those types of people become religious conservatives. The two mindsets are really very opposing. That's why so many scientists get angry at the conspiracy books that accuse them all of being the hyper-conservative "religious" types that they oppose at every turn. I think it's especially ridiculous that people think that about relativity and QM, since those things are sooo unintuitive and so uncomfortable that no one would just decide to take those things as truth without some serious questioning. The idea that "Nothing weird ever actually happens, and there's a magical energy that makes everything work" sounds
far more like the comfortable, nice belief someone would
want to hold onto against all evidence, rather than "the universe is fundamentally random and impossible to know about, composed of confusing equations that defy common sense".
I do believe there is a tendency among theoretical physicists to be caught up in mathematics and neglect observation, measurement, and experiment -- a point that Smolin makes in the book, and which is a tendency of his, too, in my opinion. As Smolin points out, a theory can be beautiful or complex or impressive mathematically without being an adequate representation of reality. One example is Ptolemy's theory of rotating circles and circles within circles to explain the motion of celestial objects around the earth.
To me, QM in general is not beautiful; it's kind of scary and depressing in some ways. I think "magical spiritual energy that permeates the universe" is far more beautiful. But it's just not true. QM was agreed to be true
despite all the scientists trying to prove it wrong. No one picked it up because they thought it would be a beautiful thing. Einstein hated it, until he was forced to accept it due to overwhelming evidence.
My own preference would be for a lot more creative experimentation and measurements to test the current theories -- this includes Einstein's relativity (both special and general) and the standard model for QM, as well as any of the current attempts to extend them, correct them, or unify them. Once any theory is established as explaining all "known" observations, that for me is a signal to start gathering new data to put it to the test. If the theory is a scientific theory, then by definition it can be tested with further observation and experiment. If a theory can't point the way to methods for testing it, that theory is immediately suspect -- not necessarily as being poor mathematics, but as not being science, which is supposed to explain what we can observe in the universe.
I agree, but scientists
have done that. The problem is it's not something you can do yourself with five dollars and some tools in your shed. Experiments in QM and relativity are beyond a common person's ability to perform; they require a lot of money, training, and the knowledge to understand what you're actually looking at and what it all means. Maybe you just need more patience

When someone comes up with a new theory that's untested, especially in something as difficult as QM, it takes a while to get those results. They are working on it, it's just a little slower than some of us would like. But still, if you think about how slow scientific discovery went from 3000 BC to 1000 BC, it's pretty amazing to see how far it's gone from 1970 to 2010.
I believe the reason there is so much effort being put into new physical theories is that there have been observations that contradict the older theories (TR and QM), and Smolin points some of these out, as well as other sources independent of him. In the meantime, it's going to be interesting to see what comes out of the new Large Hadron Collider!
There really isn't "so much effort" put into disproving relativity or QM, because the evidence is overwhelming that they are true. Most of the people who fight against it are non-scientists, and ex-scientists trying to make some money selling conspiracy theory books. String Theory is still iffy, but the basics of relativity and QM have been proven without a doubt for quite a few years now. The only people refusing to believe it are the people who either don't understand it, or think that all the evidence gathered in the last forty years is all fake and part of a conspiracy.
