Irreversibility refers to the preoperational child's tendency to "believe that what has been done cannot be undone".
Irreversibility is a phase in early child advancement in which a kid erroneously trusts that activities can't be turned around or fixed. For instance, if a three-year-old kid sees somebody straighten a ball of play dough, he won't comprehend that the batter can without much of a stretch be changed into a ball. Kids regularly develop past this phase by age seven.

One-in-two Americans are ready to drill for oil in the Arctic National Wildlife Refuge (ANWR) to lessen the country’s dependence on foreign oil, but they’re not nearly so willing to drive 55.
A new Rasmussen Reports national telephone survey finds that 50% of Adults believe the United States should produce more domestic oil by allowing drilling in the ANWR, an issue that Congress has debated for years. Thirty-five percent (35%) oppose drilling in the refuge, while 14% are not sure. (To see survey question wording, click here.)
