Do scientists use evidence?
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, although scientists also use evidence in other ways , such as when applying theories to practical problems. ...
Do scientists speculate?
Speculation is not completely forbidden in science . ... Speculation is so easy and tempting in settings where it leads more to errors than to accurate information, that most often speculation in science is discouraged. But there is still a limited, useful, role for speculation in science.
Social Science Speculation. Like natural scientists, social scientists have shown very little interest in speculation , either as a phenomenon to be studied or as a tool to be used in the analysis.

Why is speculation forbidden science?
Speculation that does not lead to experimentation is unproductive and potentially misleading . Without clever speculation, scientists would be forced to run every possible experiment, where most of the experiments would reveal nothing new or interesting.

What is the example of prediction?
The definition of a prediction is a forecast or a prophecy. An example of a prediction is a psychic telling a couple they will have a child soon, before they know the woman is pregnant.
How do you write a good prediction?
Predictions are often written in the form of “if, and, then” statements , as in, “if my hypothesis is true, and I were to do this test, then this is what I will observe.” Following our sparrow example, you could predict that, “If sparrows use grass because it is more abundant, and I compare areas that have more twigs ...
