harebrained
Wildly ill-conceived
Harebrained means reckless, foolish, or poorly thought out: a harebrained scheme, some harebrained idea about getting rich quick.
The word suggests impulsive stupidity rather than mere ignorance—acting without thinking, like a hare darting erratically.
Sometimes spelled hairbrained, though hare is the original form.
