The following are three seperate assertion instances, that assert the same proposition (that BRCA1:2685T>A causes familial breast cancer)
1. Counsyl's assertion on October 5, 2009 that BRCA1:2685T>A causes familial breast cancer.
2. The ENIGMA consortium’s assertion on September 18, 2010 that BRCA1:2685T>A causes familial breast cancer.
3. A later assertion by the ENIGMA consortium on May 9, 2013, based on new evidence, that BRCA1:2685T>A causes familial breast cancer.
The identity of a particular assertion is dependent upon (1) what it claims to be true (its semantic content, aka its ‘proposition’), (2) the agent asserting it, and (3) the occasion on which the assertion is made. Many agents can make assertions expressing belief in the same proposition (e.g. ENIGMA’s assertion that that BRCA1:2685T>A causes familial breast cancer is a separate instance than Counsyl’s assertion of the same underlying proposition). Likewise, a single agent can make more than one assertion of belief in the same proposition on different occasions (e.g. ENIGMA may make a separate assertion of the same proposition that BRCA1:2685T>A causes familial breast cancer at a later date, based on additional evidence).
SEPIO distinguishes two high-level subtypes of statements:
1. Findings are statements that report the immediate, objective results of an experiment, observation, or study - without bias or interpretation. A finding statement results simply from the act of reporting or summarizing these direct observations, calculations, or measurements.
2. Assertions, by contrast, result from acts of interpretation and/or inference, based on information used as evidence. The statement here is a conclusion drawn from critical evaluation of this more foundational information, and its validity depends on the quality of this information and the act of interpretating as evidence.
Assertions as defined in SEPIO are the result of some logical inference made based on the interpretation of evidence. They put forth a proposition that may or may not be true - the validity of which ultimately rests on the quantity, quality, diversity, and concordance of evidence supporting it.
Statements directly reporting study results or observations are not considered assertions in this sense, as they merely report what was observed or recorded, but do not rely on a leap of logical inference (see 'study finding').
A statement made by a particular agent on a particular occasion that a particular proposition is true, based on the evaluation of one or more lines of evidence.
