Fooling Yourself. | care and feeding of graduate students (life as a professor) - l to l - Top

Just taught my Halloween special lecture in computer security and am reminded about the ease of fooling yourself. The lecture itself is about some mis-leading statistics and a bit of slight of hand. The use and more importantly the design of control experiments is critical in science to help avoid fooling yourself.


Slight of hand itself is agood example of the fooling yourself. You can’t mislead your audience unless you, sort of, mislead yourself. When doing the “french drop” or the pass vanish – you have to look at where the coin or ball should be and not where it is. The magic isn’t convincing unless you look like you”re convinced too. Smoothness helps, but the audience looks where you direct them.


In science, getting the answer you want and expect is always troubling. If you aren’t wrong most of the time, then you aren’t working at the bleeding edge. You need to moral courage to keep at it. This is one of the hardest things to teach, but one of the most critical things that my students need to learn.

  3. Whether the instructions are printed or not, it never hurts to provide a tutorial for those who haven't done the job yet and are looking for some extra guidance, don't you think?

  6. you're better off using a spray bottle. this stuff works best when it enters the throttle body as slowly as possible. otherwise a nice video though.

  7. Well if Im not mistaken If you put it on the Fuel it will be better b/c it cleans the tubbing also it cleans the injectors + it goes to all the system.. The only place I have used the seafom different than that is when Im about to do an oil change I put it straight to the oil cap and let it run for about 15 min and then flush.. Thats it.. Anyone can give comments on my info that will be great..

  9. Sorry dude Seafoam doesn't go in the into the body. I goes into the main vacuum line and I hope you didn't pour the whole bottle in there. The motor should be running while you do it.
