How to use insidious in a sentence?

  1. John Grant:

    It's dangerous and the problem with this is that it's invisible, insidious and deadly, and so what you do is when a shark is in the water, you pull everyone out of the water and you make an assessment of what is going on. That's what has to happen right now, a sharp honest assessment of what is going on.

  2. Paul Mangiamele:

    What’s happening right now with other brands is an insidious disease called brand drift, these places get new CEOs and new owners with their own ideas who don’t appreciate or respect the culture and components that made these brands highfliers at one time. We’re taking dead aim at Outback Steakhouse because I think their brand is drifting. People are tired of the Bloomin’ Onion. They’re looking for something else in a value-priced steakhouse.

  3. Carla Staver:

Where it becomes insidious and problematic is that we have good evidence that it won't work, and that it's a distraction from the things that will work, (such as) making difficult decisions to cut emissions.

  4. Andrew Neil:

    Cancel culture is insidious, it stands against everything we have stood for since the Enlightenment onwards and that is why it is serious.

  5. Shannon Watts:
