Evidence for Conflicts #

Every substantive claim on the Conflicts page is checked against current research. Here is each claim, how well today’s evidence supports it, and the sources. The full, de-duplicated source list lives on the references page.

Supported · moderate evidence — Stalled learning often reflects competing motivations rather than a simple lack of motivation: the same goal can both attract and repel a person at once (approach-avoidance tension).

Approach and avoidance motivation are a long-established distinction in motivation science; Elliot’s hierarchical/2x2 models formalise that the same achievement situation can simultaneously activate approach (toward success) and avoidance (away from failure) tendencies, and approach-avoidance conflict dates back to Lewin and Miller. Treating procrastination on a wanted goal as conflict rather than deficit is well grounded, though ‘most’ stalled learning is a practical generalisation, not a measured proportion.

Supported · strong evidence — People sustain a behaviour change far better when it feels self-chosen (autonomous) than when it feels externally pressured or controlled.

A central, heavily replicated tenet of self-determination theory: autonomous (self-endorsed) motivation predicts greater persistence, maintained behaviour change and well-being relative to controlled motivation, across education, health and work. Meta-analyses of SDT-based interventions (e.g. Ng et al. 2012; Ntoumanis et al. 2021) support autonomy-supportive framing improving maintained change.

Supported · moderate evidence — Articulating in your own words why you personally want a change (rather than why you ‘should’) makes the goal more autonomous and supports following through.

SDT’s internalisation continuum holds that identifying personally meaningful reasons (‘identified/integrated regulation’) is associated with greater persistence than introjected ‘should’ reasons; autonomy-supportive techniques that elicit a person’s own rationale are a standard, evidence-backed lever. The general principle is solid; the specific act of writing it is a reasonable practical extrapolation.

Supported · moderate evidence — Resistance to learning-driven change frequently comes from the change threatening something the person already values (identity, routine, relationships), not from disliking the goal.

Basic psychological need theory holds that experiences threatening autonomy, competence or relatedness produce ’need frustration’ and defensive or avoidant responses; threats to identity and valued relationships are recognised drivers of change resistance in the self-affirmation and need-frustration literatures. The framing is well supported as a mechanism, stated qualitatively rather than as a precise effect size.

Supported · moderate evidence — Naming an internal conflict or fear, and examining it explicitly, reduces its hold and helps people act despite it.

Affect labelling—putting feelings into words—reliably dampens emotional reactivity (lower amygdala response, reduced distress) in Lieberman’s and Torre & Lieberman’s reviews, and cognitive reappraisal/exposure-based approaches show that examining a feared outcome reduces avoidance. The benefit of naming and appraising a fear is well established, with the caveat that labelling helps modestly and is not a cure.

Supported · moderate evidence — Avoidance behaviour around a wanted goal often shows up indirectly—as a steady supply of excuses or as self-sabotage and repeatedly postponing—rather than as an open decision not to do it.

Steel’s meta-analysis frames procrastination as a self-regulation failure strongly tied to task aversiveness and fear of failure, and the self-handicapping literature documents people creating excuses/obstacles to protect self-worth. That avoidance surfaces as rationalisation and postponement rather than explicit refusal is well supported.

Supported · strong evidence — Learners differ in whether they hold a mastery orientation (focused on getting better) or a performance orientation (focused on how they look), and these orientations shift with the situation rather than being fixed traits.

The mastery/performance distinction is one of the most studied constructs in educational psychology; the 2x2 framework (Elliot & McGregor) is well validated, and goal orientations are widely shown to be state-sensitive and manipulable by context/instructions, not only stable dispositions.

Supported · moderate evidence — A mastery focus tends to go with more persistence, deeper learning strategies and more enjoyment, whereas a heavy performance-avoidance focus (trying not to look stupid) tends to go with more anxiety and shallower learning.

Meta-analyses link mastery-approach goals to interest, deep strategies and effort, and performance-avoidance goals to anxiety and poorer outcomes (Huang 2011; Hulleman et al. 2010), so the direction is well established. The page correctly flags that these associations are real but modest in size and that performance-approach goals can have mixed/positive ties to attainment.

Mixed · weak evidence — Believing ability can grow (a growth mindset) is associated with more adaptive responses to setbacks than treating ability as fixed, though the average effect on outcomes is small.

Growth-mindset theory predicts more mastery-oriented, less helpless responses to failure, and a large US national experiment (Yeager et al. 2019) found small targeted benefits for lower-achieving students; however, broad meta-analyses (Sisk et al. 2018; Macnamara & Burgoyne 2023) find average effects near zero and heterogeneous, so the page deliberately states the link as real-but-modest rather than transformative.

Supported · moderate evidence — Designating a low-stakes practice space where mistakes are expected reduces the performance pressure that interferes with learning, and a fear of looking incompetent (evaluation pressure) can degrade performance.

Performance-avoidance goals and evaluative pressure are linked to anxiety and, via mechanisms like choking/working-memory disruption under pressure (Beilock & Carr 2005), to impaired performance; reframing a setting as practice/learning lowers the evaluative threat. The principle of fencing off a mistakes-allowed space is consistent with this evidence, offered as practical guidance rather than from one definitive trial.
