Crystal-balling is a term used to describe the act of predicting or forecasting future events with little to no evidence. Synonyms for this term include divining, foreseeing, prophesying, foretelling, and predicting. These terms are often associated with supernatural abilities or an otherworldly sense of intuition. Other synonyms for crystal-balling can be seen as more scientific in nature, including forecasting, estimating, extrapolating, projecting, and anticipating - each of which tend to require data and analysis to support them. No matter the term used, attempting to predict the future remains a popular and often misguided pursuit, with the past providing countless examples of failed predictions that were once thought to be certain.
