I ' m an engineer surrounded by men all my life . Throughout college and work <| sep |> Do you know what the role of profit is in an economy ? <| sep |> Interested to see if scythe , IdrisM , and Mustang Omega remain the rarest ships that were actually never sold again . <| sep |> Yeah . You hardly have to be a physicist to figure out what will happen . <| sep |> RemindMe ! 11 Months <| sep |> he so nice and so dapper and tall and is completed owned by Wall Street . They should have a beautiful bronze statue of him shaking hands with a hedge fund manager . <| sep |> The sample size is one of the most important factors . If a study was performed on 5 people , it ' s more than likely that it ' s not accurate . This is because those 5 people could be of the same type with the same interests . For example , most polls are inaccurate because they call up committed voters . And only those people respond who ' re vocal . The vocal minority gets represented in the poll , but not the majority . Also , bias and motivation is a major factor . Pharma companies influence studies that keep the competition in check until they can hit the market . Finally , interpretation matters . So , statistics are a dangerous tool in the wrong hands . You see this in politics all the time . The politicians cite only those parts of studies that help them make the case . They ' ll draw wrong conclusions . For example , you can bet that the snowfall in Tokyo will be used by climate deniers as proof that there is no climate change . To answer your question , there are no trustworthy studies because most studies begin with a goal in mind and that introduces a bias . This is why accidental discoveries and inventions are the ones that have made our lives better . Studies are only used to advance agendas .
