確固たる境界線を引く/ノーと言う

17%

直接測定されていない。実際に断固とした限界を設定する人にそれを後悔しているかを尋ねた調査はない。このバーは同一調査の満足度の数字に設定したプレースホルダーである。自称人に合わせる人の17%が、その特性によって人生が楽になったと述べている。これは人に合わせることへの満足を測定するものであり、限界を設定することへの後悔ではない。作為側の後悔率に逆転させてはおらず、この側は未測定と読むべきである

Approximately 48% of US adults who describe themselves as people-pleasers say being this way has made their life harder, while only 17% say it has made their life easier and 22% report no effect. YouGov’s August 2024 survey of 1,122 US adults established these figures; an earlier YouGov survey from June 2022 (N=1,000) found a comparable 39% reporting “life harder,” with women far more likely than men to report the trait as a net drag (47% versus 26%). The action side — regret among people who actually set firm limits — is not measured in any large representative survey, so there is no direct rate for it. The only same-survey signal is that roughly 17% of people-pleasers say the trait has made their life easier; these are the adults who would plausibly find a wholesale switch to assertive limit-setting harder. That 17% measures satisfaction with the people-pleasing behavior, not regret of boundary-setting, and is surfaced only as a proxy. Givi and Kirk (2023, Journal of Personality and Social Psychology) corroborate the order of magnitude through a different lens: across five experiments with more than 2,000 participants, people who declined social invitations systematically overestimated how angry or rejected the inviter would feel, with actual relational damage substantially below anticipated levels. If the social cost of saying no is chronically overestimated, the post-decision regret of saying no should also run lower than the anticipatory anxiety predicts.

The inaction-dominant pattern in this domain is consistent with Roese and Summerville’s foundational 2005 finding in Personality and Social Psychology Bulletin that long-term retrospective regret is dominated by things people did not do rather than things they did. Chronic over-accommodation is a sustained pattern of self-assertion inaction, and the Roese-Summerville framework predicts it will accumulate more long-term regret weight than discrete episodes of firm-limit-setting. The YouGov data tracks this prediction directly: a near-three-to-one ratio of “life harder” to “life easier” among self-identified people-pleasers, replicated across two independent surveys two years apart. The dilemma cuts across romantic, workplace, family, and social contexts — the same person who declines to push back on a partner’s request to skip therapy may also accept overtime they did not want, host family they wished would not visit, and attend social events out of guilt. YouGov does not segment by context, so the headline rates are cross-context averages.

The main caveat is that neither rate is a direct regret measurement. The 48% inaction figure is a “made my life harder” sentiment measure — adjacent to but not identical to retrospective regret. The 17% on the action side is not a regret measurement at all: it is the share of people-pleasers who say the trait made their life easier — a satisfaction measure of the inaction behavior, surfaced as a same-survey reference point rather than inverted into a regret-of-boundary-setting rate. No survey directly measures the regret of having set firm limits. The denominator on both sides is conditional on self-identifying as a people-pleaser, which is roughly half the US adult population. The population-wide inaction-regret rate is closer to 23%, but the conditional rate is the relevant figure because the dilemma only arises for adults whose default behavior is over-accommodation. The directional finding — chronic accommodation is regretted at roughly three times the rate of firm limit-setting — is consistent across two independent YouGov samples and corroborated by peer-reviewed work on invitation declining. The precise magnitudes should be held loosely.

    計算過程
    YouGov US online survey of 1,122 US adults, fielded August 26-30, 2024. The 17% figure is the percentage of self-identified people-pleasers who say the trait has made their life EASIER. It measures satisfaction with the people-pleasing (inaction) behavior; it is NOT a measurement of regret among people who set firm limits. No nationally representative survey measures the regret of people who actually set firm limits, so this side has no direct measure. We do not invert "people-pleasing made my life easier" into "regret of boundary-setting" — those are different constructs measured on a different population. The 17% is shown only as a same-survey satisfaction reference point and the entry is flagged proxy_only. Read the bar as "the action side is not directly measured," not as a measured action-side regret rate.

    Givi & Kirk (2023), Journal of Personality and Social Psychology, published online December 11, 2023 (DOI 10.1037/pspi0000443). APA press release used as the verifiable public URL; the underlying paper is paywalled. Series of five experiments with combined N>2,000 testing the anticipated-versus-actual social cost of declining invitations. Peer-reviewed finding that decliners consistently overestimate the relational damage of saying no. Used as corroborating evidence that the action-side regret rate for firm-limit-setting is plausibly low — if the social cost of declining is consistently milder than feared, the post-decision regret rate should track that pattern. Not a direct regret measurement; supports the order-of-magnitude proxy on the action side.

    計算過程
    Same YouGov 2024 survey. 48% of self-described people-pleasers (who comprise 48% of US adults overall) say being this way has made their life harder. We use this as the headline inaction-side rate because it is the closest direct survey measure of regret-equivalent sentiment toward chronic over-accommodation. The denominator is conditional: among ALL US adults, the equivalent population-wide rate is roughly 48% (self-ID rate) × 48% (life-harder rate) ≈ 23%. We use the conditional rate as the headline because the regret-pair dilemma is meaningful only for adults whose default is over-accommodation; for adults who do not over-accommodate by default, the decision does not arise. Not a direct regret measure but the tightest available sentiment anchor.

    YouGov US online survey of 1,000 US adults, fielded June 18-21, 2022. Two-year-earlier replication of the headline finding with a comparable rate (39% in 2022 versus 48% in 2024). The 47/26 gender split suggests the regret-equivalent sentiment is heavily gendered, consistent with the broader literature on unmitigated communion (Helgeson) and sociotropy. Used as a cross-time replication anchor for the 2024 headline rate.

    Roese & Summerville (2005), Personality and Social Psychology Bulletin 31(9), 1273-1285. Foundational meta-analytic finding that inaction regrets dominate long-term retrospective evaluations. Used as theoretical scaffolding: chronic over-accommodation is a sustained pattern of self-assertion inaction, and the Roese-Summerville pattern predicts it will accumulate more long-term regret weight than discrete firm-limit-setting episodes. Not a direct rate measurement; used as cross-literature support for the inaction-dominant pattern of this decision.

注意事項

どちらの率も代理指標である。48%という不作為側の率は、自認する人に合わせる人のうち、その特性によって人生が難しくなったと述べる割合を測定している。これは限界を設定しなかったことの回顧的な後悔に隣接するが同一ではない感情である。作為側には直接的な測定が一切ない。実際に断固とした限界を設定する人にそれを後悔しているかを尋ねた調査はない。その側に示された17%は、単にその特性によって人生が楽になったと述べる人に合わせる人の割合であり、これは不作為の行動の満足度の測定であって、異なる集団に対するものである。我々はこれを限界設定への後悔率に逆転させてはおらず、同一調査の参照点にすぎず、そのためこのエントリーは proxy_only と明示されている。分母は人に合わせる人であると自認すること(米国の成人人口のおよそ半分)を条件としている。人口全体の不作為の後悔率は約23%に近い。我々が条件付きの率を用いるのは、このジレンマが、既定の行動が過度に迎合的である成人にとってのみ意味を持つからである。Givi et al.(2023、JPSP)は、断る人が断ることの社会的コストを体系的に過大評価するという査読済みの証拠を提供し、これは低い作為側の後悔率と整合するが、それ自体は後悔の測定ではない。この意思決定の領域は恋愛・職場・家族・社会的文脈にまたがる。YouGov のデータはこれらの文脈を分離していないため、見出しの率は文脈特有ではなく文脈横断の平均として読むべきである。このジレンマの職場に特化した版は、声を上げるか沈黙を守るかのエントリーで別途扱っている。
