But they sure trust engineering.

Understanding the reliability of a device that you've used countless times before is not "trusting science".

a bunch of scientists got together to test a frog, They cut off one leg and yelled jump and the frog jumped, cut off another leg, yelled jump and the frog jumped the same with the next leg, then they cut off the fourth leg and yelled jump over and over and the frog did not jump. thus proving that frogs with no legs go def. you can use science to prove any thing as long as no one questions you and just trusts the science.

Is this meme referencing people who believe in the efficacy of vaccines (like for polio) that are good for life, but don't trust the efficacy of vaccines that require continual boosters and the value of ones whose side effects were covered up?
