Sounds like Wikipedia is suffering from some Buddhist fervour of its own... ;)
Can I interpret the first of the eightfold path as scientific fervor ?
Right view has nothing to do with fervour; it refers to one's outlook or point of "view". The word "diṭṭhi" literally means "way of seeing". As the commentary explains it:
The characteristic of seeing properly is right view.
In Theravada Buddhism, right view is of five kinds:
1. Right View Regarding Karma (kammassakatāsammādiṭṭhi)
“And what is accomplishment in view? Here, someone holds right view and has a correct perspective thus: ‘There is what is given, sacrificed, and offered; there is fruit and result of good and bad actions; there is this world and the other world; there is mother and father; there are beings spontaneously reborn; there are in the world ascetics and brahmins of right conduct and right practice who, having realized this world and the other world for themselves by direct knowledge, make them known to others.’ This is called accomplishment in view."
AN 3.117 (Bodhi, trans)
The Buddha calls this type of right view "affected by the taints, partaking of merit, ripening in the acquisitions" (MN 117)
2. Right View Regarding Insight (vipassanāsammādiṭṭhi)
And how does right view come first? One understands wrong view as wrong view and right view as right view: this is one’s right view.
MN 117 (Bodhi, trans)
The commentary explains that this is the understanding one gains along the path of the three characteristics (impermanence, suffering, non-self).
3. Right View of the Path (maggasammādiṭṭhi)
“And what, bhikkhus, is right view that is noble, taintless, supramundane, a factor of the path? The wisdom, the faculty of wisdom, the power of wisdom, the investigation-of-states enlightenment factor, the path factor of right view in one whose mind is noble, whose mind is taintless, who possesses the noble path and is developing the noble path: this is right view that is noble, taintless, supramundane, a factor of the path.
MN 117 (Bodhi, trans)
4. Right View of Fruition (phalasammādiṭṭhi)
The right view of fruition is the same as the right view of the path.
5. Right View of Reflection (paccavekkhaṇāsammādiṭṭhi)
“When I knew and saw thus, my mind was liberated from the taint of sensual desire, from the taint of being, and from the taint of ignorance. When it was liberated, there came the knowledge: ‘It is liberated.’ I directly knew: ‘Birth is destroyed, the holy life has been lived, what had to be done has been done, there is no more coming to any state of being.’
MN 4 (Bodhi, trans)
This refers to the knowledge that comes after attainment of enlightenment upon reflection of the path and fruition.
Further, Ven. Sariputta equates right view with knowledge of the four noble truths:
“And what, friends, is right view? Knowledge of suffering, knowledge of the origin of suffering, knowledge of the cessation of suffering, and knowledge of the way leading to the cessation of suffering—this is called right view."
MN 141 (Bodhi, trans)
Since there is no scientific evidence to rebirth, would believing in it make my belief dogmatic or narrow minded maybe?
However you come to the understanding that rebirth is a fact of life, that understanding is considered right view, insofar as it is in line with the truth. If you believe that at death the mind ceases, or that at death the same mind that existed before death continues on, both of these are wrong view.
As according to the quotes above, right view can be "affected by taints" if it is simply belief that happens to accord with reality, or it can be "noble, taintless, supramundane, a factor of the path" if it is acquired through observation and understanding.
Rebirth really isn't a big mystery; it is simply the fact of existence that is perfectly open to reasonable scientific investigation that everything in the universe arises and ceases, and that certain arisen phenomena spawn further arisen phenomena in an unbroken causal chain. That this ceases at death is wrong view (ucchedaditthi); that this constitutes a lasting, continuous entity is also wrong view (sassataditthi).
