In American business and scientific contexts, 'zero effect' is frequently used in reports, studies, and casual conversation to describe failed initiatives or ineffective interventions. In Brazil, the expression is becoming more common in corporate environments, though traditional phrasing with 'efeito nulo' remains more formal. The phrase reflects a quantitative, results-driven culture in both English-speaking and Brazilian Portuguese-speaking business environments.
