A 2026 paper in the Journal of Family Theory & Review makes a case that should feel familiar: new fathers experience genuine fear — of failing, of being shut out, of losing their partner — but decades of masculine socialization mean most can't identify the emotion as fear. Instead it comes out as irritability, emotional shutdown, or just… disappearing into work.
The paper, by Sabey et al., argues that therapists and researchers consistently underestimate how much fear underlies fathers' behavior in the transition to parenthood. Men who grew up learning that fear equals weakness don't stop feeling scared — they just reroute it. The result: a dad who looks checked-out or defensive is often a dad who's frightened and has no language for it.
This lands differently when you're in it. If your partner is frustrated that you seem distant, and you genuinely don't know why you feel the way you do — this might be part of it. It's not that you don't care. It's that the internal alarm is firing, and you were never taught what the alarm means.
The researchers also point to attachment theory as the missing frame: fathers' early attachment histories shape how they respond under stress, and most never get the chance to examine those patterns before the baby arrives and everything accelerates.
