The ‘wood wide web’ may be a better metaphor than fact.
Mycorrhizal networks are real. Some of the stories we tell about what forests do through them outran the field evidence.

Common mycorrhizal networks can connect roots of multiple plants.
Some popular accounts overstate what the field evidence establishes about resource transfer and cooperation.
Forest-wide intentional cooperation is a compelling story, not an established mechanism.
A beautiful metaphor became too easy to repeat.
A 2023 evidence review examined several popular claims about common mycorrhizal networks in forests and argued that claims of widespread resource transfer and preferential support for kin were often overstated relative to field evidence.
A vivid explanation can become more certain every time it is retold, even while the underlying network is real and the stronger story outruns the field evidence.
The most interesting correction is often not false. It is more uncertain than the story we learned.
Think with the idea.
Take me sideways
The same mechanism appears in business and technology: a metaphor begins as a useful compression, then hardens into an explanation people stop checking.
Cross-domain interpretation.Challenge it
A correction paper can itself be overgeneralized. Evidence being weaker than popular accounts does not mean ecological networks are unimportant.
Counterpoint to avoid reverse-mythologizing.Trace it
Trace the claim from primary ecology research to popular science, books, talks and social media. Watch where uncertainty disappears.
Editorial research path.Make it useful
Whenever a story is unusually elegant, look for the original evidence before repeating the metaphor as mechanism.
Epistemic habit.
