The WTS in recent years has placed most of the blame on Adam rather than Eve but it still sneaks in.

w97 6/15 p. 15 par. 5 "Male and Female He Created Them" ***But Adam did not live up to his responsibility, and Eve used her femininity in a persuasive way to entice Adam to join her in disobeying God. (Genesis 3:6)
By allowing himself to do what he knew was wrong, Adam failed to display true masculinity. He weakly chose to accept the word of his deceived mate instead of what his Father and Creator had said. (Genesis 2:16, 17)
*** w92 10/15 p. 6 Family Distress—A Sign of the Times ***God decreed that Adam was to be the head of the family. Eve was to cooperate with his headship as his "helper," or "complement." But Eve rebelled at this arrangement. She usurped her husband’s headship and disobeyed the one and only prohibition God had placed upon them. Adam then abdicated his headship and joined her in this revolt.—Genesis 1:26–3:6.
*** it-2 p. 521 Obedience ***The willful disobedience of the perfect man Adam, as the responsible head over Eve and as the male progenitor or life source of the human family, brought sin and death to all his offspring.
*** Life Purpose 1977 chap. 5 p. 59 par. 37 Why Has God Allowed Suffering on Earth? ***Adam’s self-excusing reply blamed the woman as the guilty one. But Adam was fully responsible, and, as head of his household, he was the one with whom God dealt directly. He was reprehensible.
*** w56 9/1 p. 538 par. 14 Marriage Under Imperfect Conditions ***In the first place, the failing of the first man and his wife to love God unitedly and more than each other. Along with lack of love for God and as a result of it, each one failed to respect the God-assigned places of husband and wife in the marriage arrangement and to live up to the responsibilities and the obligations of that place. Adam, as the head, was foremost in responsibility for all this. Pointing to him as chiefly responsible for all the sinfulness and death that have come to us who have been born as a result of their damaged marriage, the Word of God the Judge says: "Through one man sin entered into the world and death through sin, and thus death spread to all men because they had all sinned— . . . death ruled as king from Adam down." (Rom. 5:12-14, NW)
