Which is the most likely a reason why?
a tobacco company funded amelia to run experiments and
publish a paper. she spent a year completing several
experiments to find a way to process tobacco leaves that
would be better for health. amelia conducted controlled
experiments, and her results were the same each time.
when scientists began conducting peer review, several of
them were concerned that the results would be biased
her funding was from a source that could profit from the
results
she did not carry out the experiments for the minimum
of 5 years
most scientists do not conduct research on tobacco
products
her results should have shown variation in the outcome

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
