In more detail
A Theoretical connection marks an association you are proposing rather than one you can point to in shared codes. It might come from the literature, from a theoretical lens, or from an interpretation you want to test against the data.
Marking these links as dashed keeps them visible without presenting them as evidence. Like an Empirical connection, it carries a note and can carry an arrow pointing to the effect.
In Themescape
Add a branch in Work mode and choose Theoretical, or write theoretical in the type column of the Connections tab. Any value containing "theor" is read as theoretical, so the viewer's own export wording, theory, works too.
A short example
From the Working Well dataset
Connection and Isolation
Working definition: Feeling out of the Loop to Being Trusted to Deliver: trust without information can still leave someone isolated.
Feeling out of the LoopBeing Trusted to Deliver
A Theoretical connection across two themes, Connection and Isolation and Autonomy and Trust, as recorded in the Working Well sample. Made up data, nothing from a real study.
