You can use it when discussing a theory, argument, or hypothesis that requires backing or evidence.
Example: "The research findings are consistent with the existing literature and support the postulate that early intervention leads to better outcomes."
Alternatives: "and reinforce the assumption" or "and validate the hypothesis".
As Zhang and Meadows (2012) noted in their triangulation of agendas of the White House, media and public: "Our findings support the postulate that the news media is a diplomatic device as powerful as formal policy statements.
A majority of the in vitro and animal model investigations support the postulate that transition metals present in ROFA (especially vanadium) participate in Fenton-like chemical reactions to produce reactive oxygen species.
Collectively, the genomics-driven approach to identification of tumor-specific neo-epitopes has just begun and is beginning to support the postulate [ 34] that (a) tumors do harbor an individually distinct repertoire and (b) that this repertoire is created by randomness of passenger mutations.
For our maternal transmission model, we conclude that the data do not support the postulate that IL-4 and 13 cross the placenta under these experimental conditions.
The same authors, however, found the effect to be tissue specific and noted that ubiquitous expression of hUCP2 failed to extend lifespan, failing to support the postulate (Fridell et al., 2005).
The results of the survey-based research do not support the postulate that an interactive use of MCS favours innovation.
Our results also do not definitively support the postulate that focal imaging patterns may predict improved clinical outcomes by reflecting Y-90 localisation to areas of synovial disease activity [12, 13].
In contrast to neurons, our data using RhodZin-3 as a mitochondrial Zn biosensor do not support the postulate that mitochondria serve as a rapid hormonally-regulated mobilizable Zn pool in mammary cells.
Our findings offer the first ever evidence to support the postulate that cross reactivity of antibodies against C-terminal sequences of ribosomal P proteins from several animals, plant and protozoal with heart tissue may mediate EMF in a similar manner as C- termini of T. cruzi do for Chaga's disease.
These results support the postulate of Hayakawa et al. that the products of hAS3MT are trivalent, not pentavalent.
