How to use unsound in a sentence?

  1. Justice Samuel Alito:

    Too much public discourse today is sullied by ad hominem rhetoric, that is, attempts to discredit an argument not by proving that it is unsound but by attacking the character or motives of the argument's proponents, the majority regrettably succumbs to this trend.

  2. Lindsey Graham:

    For a federal mandate to come about for measles or any other particular illness or disease you'd have to convince me it was necessary, but the question is, is there scientific evidence to justify a politician suggesting that vaccinations programs we have today are unsound? My answer is no.

  3. Hassan Rouhani:

    The Americans do not know our region. That's the problem. Those who are advising the Americans are unfortunately rulers who deviate America with unsound advice or buy some influence in the US with their money.

  4. The University of Chicago:

    Partial data from an ongoing clinical trial is by definition incomplete and should never be used to draw conclusions about the safety or efficacy of a potential treatment that is under investigation, in this case, information from an internal forum for research colleagues concerning work in progress was released without authorization. Drawing any conclusions at this point is premature and scientifically unsound.

  5. Eliot Engel:

    There's a reason the Obama administration and The Trump administration, at least before this point, never made such audacious legal claims. The assertion that Congress has authorized the executive branch to use force against Iran is unsound. A bipartisan majority of both houses of Congress have rejected that view in just the past few weeks through congressional findings, the administration's position is dangerous. It holds Iran directly responsible for abuses committed by armed groups under a new-fangled theory that United States would not want to see applied to our support for armed forces including the Saudi bombing campaign in Yemen and the Syrian Kurdish forces' treatment of detainees.
