当(あ)て推量(ずいりょう)

あてずいりょう
noun
guesswork; conjecture
abstract
1. guesswork; conjecture; random guess
A guess made without solid evidence or basis; speculation based on little information. Often carries a slightly negative connotation, implying the guess is unreliable.

It is dangerous to decide on a culprit based on guesswork without evidence.

当(あ)て means 'aim' or 'guess,' and 推量(すいりょう) means 'conjecture' or 'inference' (the reading changes to ずいりょう in this compound). 当(あ)て推量(ずいりょう) emphasizes that the guess is unfounded — a shot in the dark rather than a reasoned deduction.
