Difficult isn't the word I would use. It is impossible to draw meaningful conclusions without careful observation and experimentation, and it would be dangerous to try, because there be the monsters of error in those waters. You might get lucky once, but it isn't about luck. Guessed answers aren't useful, and answers not based on observation and experiement are nothing more than guesses.
Yes, just be careful!
dust can make you cough badly if your not careful
be careful!!
Good scientists must be careful when predicting results from their studies because they know that always there is a chance of something go wrong.

Experimentation.
the archaeologlat is the careful uncovering of evidence
Experimentation means trying something to see what happens. When this is done by scientists, experiments can be complex, and very careful measurements and observations are used to learn as much as possible. Nonetheless, they are still trying something to see what happens.
Faulty conclusions may be drawn when they're based upon too few facts or observations. In science, a conclusion is arrived at after a careful search for available, reliable information. That information is dependable when it's based on the careful trial and error recording of experiments, interviews and observations.
science- is a systematized body of knowledge based on careful observation and experimentation to searched the truth -came from latin word scire means to know
They want to make sure an observed difference isn't due to chance
You need to perform some experimentation first. Based on that you need to be very careful of what is happening in front of your eyes. It is what you think will happen next but it definitely cannot be a free prediction
Because a scientist need serious, reproductible, reliable data to elaborate a theory, to emit conclusions etc..
Given that psychology is essentially a study of psychic abilities and the paranormal, it proves difficult to be tested. Psychology is a science, requiring careful experimentation and research to truly justify any findings in its studies. Parapsychology has yet to show extraordinary, or for that matter, concrete evidence to justify existence of the paranormal, or for it to obtain any credibility as a true science.
Scientific experimentation includes all of the above.
