To absence of certainty It is called uncertainty . The certainty , in turn, is associated with evidence and certainty.
This means that when someone goes through a moment of uncertainty, lacks reliable knowledge or definitions about something. For example: "There is uncertainty in the government because, according to several pollsters, the vote will be very close", "The increase in the dollar creates uncertainty among consumers", "Uncertainty in the coaching staff: the team captain withdrew from training with a discomfort in his left knee".
Uncertainty is linked to nervousness or to the restlessness . Take the case of a young man who attends a job interview. The boy meets with the owner of the company for one hour: at the end of the meeting, the businessman tells him that the next day he will contact him again to inform him if the position is his or if, on the contrary, he chose another applicant. The young man, in this way, lives hours of uncertainty because he doesn't know if he will get the job or not . He has no way of knowing, for the moment, the result of the selection process.
It is common for uncertainty to appear on multiple issues of daily life, in all areas. This is because the future cannot be predicted exactly. However, through certain analyzes, many times they can be performed forecasts that contribute to reduce uncertainty.
In the economy , uncertainty is considered as something negative. Investors expect predictability in the markets since, in this way, they can minimize risks and increase the possibility of obtaining benefits. When there is economic uncertainty in a country, they usually decide not to invest.
