Intelligence
Fallout 76 S.P.E.C.I.A.L.

Intelligence is one of the 7 S.P.E.C.I.A.L. stats in Fallout 76, allocated from 1 to 15 points as you level. Intelligence is a measure of your overall mental acuity, and affects your ability to hack terminals, the condition and durability of items that you craft, and the return you get from scrapping. Each point of Intelligence adds 3% XP gain.

It has 34 Intelligence perks. Every equipped card spends Intelligence points, so the stat caps how many perks you can run at once. 5 perks scale with Intelligence itself, so the bonus keeps growing on buffed points past 15. The legendary perk Legendary Intelligence raises it beyond your allocation, adding up to 5 Intelligence and 5 Intelligence perk points at its top rank. On top of allocated points, 38 consumables, 9 gear mods, 3 mutations, 2 addictions and 3 perks raise or lower it.
