Perspective taking was the only intervention that significantly reduced explicit stereotypes, whereas none of the brief interventions shifted implicit ageism, indicating that implicit bias may require more sustained or repeated efforts.
Key Findings
Results
Perspective taking was the only intervention that significantly reduced explicit ageist stereotypes compared to the control condition.
The study compared three intervention methods: exposure to counter-stereotypical traits, perspective taking, and implementation intention
Only perspective taking showed a statistically significant reduction in explicit ageism measures
The other two interventions (counter-stereotypical traits and implementation intention) did not significantly reduce explicit stereotypes relative to control
The study used a one-factor between-subjects design with N = 184 participants
Results
None of the three brief interventions produced a significant shift in implicit ageism as measured by the Implicit Association Test.
Implicit ageism was measured using an Implicit Association Test (IAT) with N = 174 participants
The IAT tested associations between old and young faces with age-related hate speech and friendly comments
All three intervention conditions failed to significantly alter implicit ageist bias compared to control
The authors suggest implicit bias may require more sustained or repeated intervention efforts
Results
Aging anxiety did not moderate the effectiveness of the interventions on ageism outcomes.
Aging anxiety was examined as a potential moderator of intervention effectiveness
No significant moderation effect of aging anxiety was found across any of the three intervention conditions
The null moderation result held for both explicit and implicit ageism outcomes
Results
Aging anxiety predicted explicit ageism independently of intervention condition.
Although aging anxiety did not moderate intervention effectiveness, it emerged as a significant predictor of explicit ageism
This suggests aging anxiety is a relevant individual-difference variable in the expression of explicit ageist attitudes
The predictive relationship was found after accounting for the intervention conditions
Background
The COVID-19 pandemic exacerbated ageism, evidenced by an increase in ageist hate speech on social media, motivating the study of online interventions.
Globally, one in two people discriminates against older adults according to the authors' framing
The pandemic context highlighted the urgent need to combat ageism in digital spaces
The study was designed to identify effective online interventions targeting both ageism and hate speech
The three intervention methods were selected based on their differential targeting of explicit versus implicit ageist biases
Methods
Contact with older adults was examined as a potential influencing factor on intervention effectiveness alongside aging anxiety.
The study assessed contact with older adults as one of several potential moderating or confounding variables
This factor was examined in the context of whether it affected the relative effectiveness of the interventions
The inclusion of contact variables reflects established intergroup contact theory applied to ageism research
What This Means
This research suggests that not all anti-ageism interventions work equally well, and that the type of bias being targeted matters. In an online experiment with 184 participants, researchers tested three brief strategies meant to reduce prejudice against older adults: having people read about counter-stereotypical traits of older adults, asking them to take the perspective of an older person, and having them form specific plans (implementation intentions) to act less ageistically. Only the perspective-taking approach — mentally imagining life from an older adult's viewpoint — meaningfully reduced people's consciously held ageist stereotypes. None of the three brief interventions changed people's unconscious (implicit) biases, which were measured using a reaction-time test linking older and younger faces to hateful versus friendly language.
The study also found that how anxious people feel about their own aging predicted how explicitly ageist they were, though this anxiety did not change how well the interventions worked. The finding that implicit biases were untouched by any single brief session suggests that deeply ingrained automatic associations require longer-term or repeated interventions to shift, whereas conscious attitudes may be more responsive to shorter online tasks.
This research matters because ageism is widespread — affecting roughly one in two people globally — and has worsened in online environments during and after the COVID-19 pandemic. The results suggest that scalable online interventions like perspective taking could be a useful tool for reducing conscious prejudice against older adults in digital spaces, but that tackling deeper, automatic biases will likely require more intensive and sustained efforts.
