Lie in the context of "Under oath"

Economic materialism, known colloquially simply as materialism, is a personal attitude that attaches importance to acquiring (and often consuming) material goods. The use of the term "materialistic" to describe an individual's personality or a society tends to have a negative or critical connotation. Rarely also called acquisitiveness, it is often associated with a value system that regards social status as being determined by affluence (see conspicuous consumption), as well as the belief that possessions can provide happiness, which has been critiqued as a lie brought about by capitalism. Environmentalism can be considered a competing orientation to materialism.

The definition of materialism coincides with how and why resources to extract and create the material object are logistically formed. "Success materialism" can be considered a pragmatic form of enlightened self-interest based on a prudent understanding of the character of market-oriented economy and society.

To be economical with the truth literally means to avoid revealing too much of the truth. While the idea may have an approbatory sense of prudence or diplomacy, the phrase is often either used euphemistically to denote dissimulation (misleading by withholding pertinent information) or else used ironically to mean outright lying. The term parsimonious with the truth is also sometimes used in the same way.

Post-truth politics, also described as post-factual politics or post-reality politics, amidst varying academic and dictionary definitions of the term, refer to a recent historical period where political culture is marked by public anxiety about what claims can be publicly accepted facts.

It suggests that the public (not scientific or philosophical) distinction between truth and falsity—as well as honesty and lying—have become a focal concern of public life, and are viewed by popular commentators and academic researchers alike as having a consequential role in how politics operates in the early 21st century. It is regarded as especially being influenced by the arrival of new communication and media technologies. Popularized as a term in news media and a dictionary definition, post-truth has developed from a short-hand label for the abundance and influence of misleading or false political claims into a concept empirically studied and theorized by academic research. Oxford Dictionaries declared that its international word of the year in 2016 was "post-truth", citing a 20-fold increase in usage compared to 2015, and noted that it was commonly associated with the noun "post-truth politics".
