I think one reason is that organizations often treat lessons learned as records of the past rather than inputs into future decisions.
Capturing a lesson does not create organizational learning by itself. The real test is whether that lesson changes a decision rule, a planning assumption, a risk trigger, a governance threshold, a checklist, or the context available to the next team facing a similar situation.
Otherwise, the organization may remember what happened without changing how it decides.
For me, the key question is not only whether lessons are stored or reused. It is whether the system can recognize when a past lesson has become relevant to a present decision.
Perhaps organizations repeat mistakes because they have repositories of lessons, but not a living memory connected to decision-making.

The distinction between documenting a lesson and changing how future decisions are made really resonates. I've found that lessons become much more valuable when they influence templates, checklists, or governance instead of remaining as standalone records.
Most organisation have broken systems, when the system is broken - it becomes difficult to implement recommendations and lessons learnt.

Right, even the best lessons won't lead to change if the surrounding processes don't support putting those recommendations into practice. That's an important perspective.
Make the lessons learned part of your project implementation checklist. Otherwise, it will be overlooked, as is often the case.

Embedding lessons into implementation checklists is a practical way to keep them visible. It turns learning into part of the workflow instead of something that's only revisited at project closure.

This is truly the most real and often overlooked pain point in project management! Many times, we merely 'record' the lessons learned, without internalizing them into the organization's DNA.
Completely agree with your observation; this essentially depends on the organization's culture and attitude. If senior management only focuses on resolving immediate crises and neglects long-term knowledge reuse, the same mistakes will inevitably keep repeating themselves. This problem is difficult for a project manager to reverse on their own.
In my view, to truly improve this situation, a culture of valuing and prioritizing learning must be established 'from top to bottom,' and even transformed into a 'system.' For example, formally incorporate Lessons Learned reviews into the new project initiation process, or make it a necessary condition for periodic reviews.
Only when the organization establishes a system that 'allows for reflection and mandates reuse' can lessons learned truly have value, and not just be a line of text in the closing report.

Your point about turning learning into a system is key. When reviewing past lessons becomes part of project initiation rather than an optional activity, organizations are much more likely to avoid repeating the same mistakes.
In my experience, the issue is rarely capturing lessons, it is applying them. Lessons learned should be reviewed during project initiation, planning, and key stage gates, not only at closure. When teams make past insights part of decision making and governance, they become organizational knowledge instead of archived documents.

Yeah, reviewing lessons at key decision points instead of only at project closure can make a significant difference. It keeps previous experience connected to the decisions teams are making today.
Making lessons learned easily accessible enables project professionals to review past issues, mistakes and decisions, helping them stay focused on the current scope and address challenges more effectively. For example, maintaining a centralized repository of lessons learned, risks, issues, and decision logs as an active knowledge base rather than a historical archive is far more valuable. The repository can be queried or connected to dashboards for analysis, and integrating it with project management tools embeds it into the project workflow. This encourages project professionals to regularly reference past experiences, identify recurring patterns and apply proven solutions before similar issues arise.

Connecting lessons learned to project management tools is a great way to encourage their reuse. The easier they are to find during day-to-day work, the more likely teams are to apply them instead of recreating the same solutions.
