This result emphasizes the urgency of reliable sources of information that accurately and precisely represent objective reality as the ground truth.This brings us back to the question about accuracy and precision of our information sources. Here are definitions of precision by the dictionary.
the quality, condition, or fact of being exact and accurate.And here are the definitions of accuracy.
"the deal was planned and executed with military precision"
refinement in a measurement, calculation, or specification, especially as represented by the number of digits given.
"a precision of six decimal figures"
the quality or state of being correct or precise.
"we have confidence in the accuracy of the statistics"
the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard.
"the accuracy of radiocarbon dating"
We can see here that in general definition, the meanings of precision and accuracy are mixed. While in technical definition, it's restricted to numeric writing, especially in decimal based number. We can quickly realize that those definitions can't cover all kinds of usage of the word.
In technical usage, non-number information can't be described. For example, Alice is going to Japan. It would be more precise if it's said that she's going to Tokyo. Even more precise if the district or even the complete address were given. But if it turns out that she's going to Kyoto instead of Tokyo, then the previous information about the destination city is not accurate, although still more precise than just the destination country.
Expression of the same numeric value but in different base number would give us different precision.
In general usage, it should be possible to express information with high precision independently from accuracy. There are accurate but imprecise information. On the other hand, there are also precise but inaccurate information.
This video tries to distinct them.
