A more thorough explanation:

Definition: lacking foresight and care in the management of property; of or relating to a judgment arrived at by using misleading information or a mistaken assumption.

1. John was an improvident spender, always buying things he didn't need and not saving any money for the future.

2. The company's decision to invest in a failing business was improvident, as they lost a significant amount of money.

3. The politician's statement was based on improvident assumptions, leading to misinformation being spread.

These examples illustrate how being improvident can lead to negative consequences. In the first example, John's lack of care in managing his finances led to him not having any savings for the future. In the second example, the company's decision to invest in a failing business resulted in them losing money. In the third example, the politician's statement was based on misleading information, which could have led to negative consequences if people had believed it.
