If you feel you should already know the answer, psychological safety can make it easier to ask, check an assumption, admit a mistake, or disagree without fearing humiliation or punishment. It is not a confidence trick or a promise to eliminate impostor feelings: it is a shared team belief that interpersonal risk-taking is safe, supported by clear expectations and accountable work.
What psychological safety means on a software team
Psychological safety is about what happens when someone takes an interpersonal risk: asking a basic question, surfacing a concern, acknowledging uncertainty, or challenging a decision. A safer team does not avoid disagreement, lower engineering standards, or excuse missed responsibilities. It makes it possible to discuss those things openly and constructively.

Google re:Work describes psychological safety as one of five team dynamics, alongside dependability, structure and clarity, meaning, and impact. The guide reflects Google’s internal team research, not a universal ranking that applies identically to every engineering organization. Google re:Work’s team-effectiveness guide also notes that factors not significant in its analysis may matter in other settings.
For developers, the useful test is behavioral: can a teammate say “I don’t understand this requirement,” flag a production risk, or explain that a change introduced a bug—and get a response focused on understanding and resolving the issue rather than shaming the person?

How common are impostor feelings among software engineers?
A 2023 survey study, Impostor Phenomenon in Software Engineers, received responses from 624 software engineers in 26 countries. The authors reported frequent-to-intense impostor feelings among 52.7% of respondents; the reported proportions were 60.6% for women and 48.8% for men. These are results from that survey sample, not prevalence estimates for all developers. The figures describe respondents’ reports, not a diagnosis. The study’s arXiv record identifies it as a preprint, so it should not be described as peer reviewed on the basis of that record alone.
Impostor feelings can make ordinary learning moments—asking for context, requesting review, or saying “I might be wrong”—feel like evidence of incompetence. A team cannot resolve that experience solely by telling individuals to be more confident. Individual coping and team conditions matter together, and the available evidence does not show that psychological safety eliminates impostor feelings.
What software-team studies suggest about safety and performance
Autonomy, reflection, and team outcomes
A 2021 survey of 236 members across 43 software-development teams in Norway modeled relationships among work design, psychological safety, and team outcomes. The authors reported autonomy as a contributor to psychological safety and reported that safety was associated with team reflexivity and team performance. This is evidence of modeled relationships in a survey, not proof that a particular intervention causes better performance. Buvik and Tkalich’s study examines these relationships in agile software-development teams.

Norm clarity matters alongside safety
A 2018 survey across 38 software teams in five Swedish organizations found that psychological safety and clarity of team norms predicted members’ self-assessed performance and job satisfaction. In that sample, norm clarity was the stronger predictor. That finding makes the two conditions complementary: people need room to speak up, and they benefit from knowing how questions, review feedback, risk escalation, and mistakes are handled. Lenberg and Feldt’s study reports the survey findings.
The evidence base is developing
A 2025 systematic review of psychological safety in software workplaces identifies antecedents at individual, team, and organizational levels, including autonomy, agile practices, and leadership behavior. It summarizes reported benefits related to learning, innovation, team performance, software quality, and job satisfaction, while noting gaps in understanding context, mechanisms, and practical ways to improve safety. The review is a synthesis of a still-limited research area, not proof that a single team exercise will produce those outcomes. Santana and colleagues’ review provides the overview.
How to ask for help when you feel you should already know
Make the request specific and tied to the work. The goal is not to perform certainty; it is to get enough information to make a sound decision.
- Name the uncertainty: “I’m not sure whether this change should preserve the existing retry behavior.”
- Show what you checked: “I traced the caller and read the tests, but I can’t tell whether this timeout is intentional.”
- Ask for a concrete next step: “Can you point me to the decision or help me verify the expected behavior?”
- Raise risk early: “I think this could affect existing sessions. Can we check the migration path before merging?”
- Invite correction without surrendering judgment: “Here is my reasoning; what am I missing?”
A useful private prompt is: “What information or feedback would help me check this assumption?” The matching team-level question is: “Have we made it safe and normal to ask this here?” If the same question feels risky every time, the answer is not necessarily to try harder as an individual; the team may need clearer norms or a different response to questions.

What leaders and teams can change in practice
Psychological safety is a shared belief, so it is shaped by repeated interactions—not just a statement of values or a one-time workshop. The practices below are reasonable applications of the research on safety, norms, and leadership; the studies do not establish one universally best intervention.
Respond to uncertainty and mistakes with inquiry
When someone raises a problem, first establish what happened and what the team needs to learn. Ask what assumptions, signals, or process conditions contributed; then agree on corrective action and ownership. Accountability remains important, but blame that discourages people from sharing information can make it harder to detect and address problems.
Rank #4
Make working norms explicit
Agree on practical expectations: where to ask questions, how quickly reviewers should respond, how to mark a blocking concern, when to escalate a risk, and how to discuss a mistake. Spell out how decisions are made and where the rationale is recorded. Clear norms reduce the guesswork that can make a newcomer or an uncertain teammate hesitate.
Invite disagreement and explain decisions
Leaders can ask for missing perspectives before a decision is final, especially from people who will implement or support the change. When the team chooses a different option, explain the criteria and trade-offs. Respectful disagreement is compatible with alignment on the final decision; silence is not the only evidence of agreement.

Autonomy was associated with psychological safety in the Norwegian software-team survey. In practice, teams can clarify the boundaries of a decision while letting the person closest to the work investigate options and raise concerns. Delegating responsibility without authority or context is not the same as useful autonomy.

How to tell whether a change is helping
Do not judge the result only by whether people say they feel more confident. Match the measure to the change and look for both perceptions and observable work behaviors.
| What the team changes | What to observe | What the evidence can tell you |
|---|---|---|
| Individual prompts or coaching | Whether a person can identify the assumption, question, or feedback they need | May show a change in an individual’s approach; it does not establish that the team is safe to speak up. |
| Team norms for questions, review, and escalation | Whether people know where and how to raise issues, and whether responses follow the agreed process | Shows whether expectations are clearer and more consistently used. |
| Leader response to concerns and mistakes | Whether concerns receive inquiry and follow-up, and whether people raise issues earlier | Can reveal changes in interaction and learning behaviors; it does not by itself prove an effect on delivery or well-being. |
| Broader team or organizational changes | Perceptions of safety and norm clarity alongside learning, delivery, and well-being indicators | Provides a fuller picture, but multiple factors can influence these outcomes. |
Use a baseline and revisit the same questions or behaviors after changes have been in place. Interpret results in context: a rise in reported issues, for example, could reflect more willingness to surface problems rather than worsening engineering practice. The available studies do not validate a single measurement method or intervention as best for every team.
Why safety is part of dependable engineering work
Psychological safety is not a substitute for secure practices, sound technical processes, or clear responsibility. DORA’s 2022 research summary reports that teams with low levels of security practices had 1.4 times the odds of high burnout compared with teams with high levels of those practices. It also reports that teams with high levels of security practices were 1.6 times more likely to have high organizational performance. These comparisons concern security-practice levels; they are not estimates of the effect of psychological safety alone. DORA also emphasizes that context affects how capabilities work. DORA’s 2022 research summary explains the findings.

The 2025 DORA report announcement says its findings draw on more than 100 hours of qualitative data and survey responses from nearly 5,000 technology professionals. It reports that 90% of survey respondents use AI at work, more than 80% believe it increased their productivity, and 30% report little or no trust in AI-generated code. Those figures concern AI use and trust, not impostor feelings or psychological safety. DORA’s framing is that “AI doesn’t fix a team; it amplifies what’s already there.” Google Cloud’s announcement of the 2025 DORA Report gives the context.
