Infallibility belongs in a special way to the pope as head of the bishops (Matt. 16:1719; John 21:1517). As Vatican II remarked, it is a charism the pope “enjoys in virtue of his office, when, as the supreme shepherd and teacher of all the faithful, who confirms his brethren in their faith (Luke 22:32), he proclaims by a definitive act some doctrine of faith or morals. Therefore his definitions, of themselves, and not from the consent of the Church, are justly held irreformable, for they are pronounced with the assistance of the Holy Spirit, an assistance promised to him in blessed Peter.”

And the pope may uniquely claim infallibility as an individual when speaking in accordance with this criteria.
And nothing you said refutes what i had said.
Now wait a ding-dang minute!
I've come away from FR many times after being told it's the MAGISTERIUM's decision making process that's infallible!!
