The saying points to the need to improve data quality in, for example, programming. '''Rubbish in, rubbish out''' ('''RIRO''') is an alternate wording.<ref>{{Cite web |last=Demming |first=Anna |date=2019-06-30 |title=Machine learning collaborations accelerate materials discovery |url=https://physicsworld.com/a/machine-learning-collaborations-accelerate-materials-discovery/ |access-date=2019-09-18 |website=Physics World |language=en-GB}}</ref><ref>{{Cite book|url=https://books.google.com/books?id=tb43AAAAQBAJ&q=RIRO&pg=PP1|title=The Art of Creative Thinking: How to be Innovative and Develop Great Ideas|last=Adair|first=John|date=2009-02-03|publisher=Kogan Page Publishers|isbn=9780749460082|language=en|author-link=John Adair (author)}}</ref> | ||
The principle applies to all logical [[Argumentation theory|argumentation]]: [[soundness]] implies [[validity (logic)|validity]], but validity does not imply soundness. | The principle applies to all logical [[Argumentation theory|argumentation]]: [[soundness]] implies [[validity (logic)|validity]], but validity does not imply [[soundness]]. In other words, assumptions matter: even if someone is perfectly logical, when they start with false assumptions, they can get a false result. | ||
