Why did the donner party use the Hastings cutoff when it was dangerous?

The Donner Party chose to use the Hastings Cutoff primarily due to the promise of a shorter route to California, which they believed would save time and resources. They were influenced by misleading information from Lansford Hastings, who promoted the cutoff as a more direct path despite its challenging terrain. The allure of reaching their destination faster led them to overlook the potential dangers and difficulties associated with the untested route. Ultimately, this decision contributed to their tragic fate in the Sierra Nevada.
