A truly scientific mind is not too lazy to do research before arriving at a conclusion.
And a logical mind does not purport no evidence exists simply because its owner has not happened to stumble across it.
========
Try, for example:

A study which involved the FAA, experts in aviation medicine, and an Air Force research lab
=========
Or the case of Dana Christian Welch, sentenced to 30 months in 2009 for pointing a laser at large, commercial aircraft, resulting partly in the actual delay of a critical landing maneuver by an Alaska Airlines jet.
This was not an instance of anecdotal reporting by some hysterical, "unreliable" (to use your word) single pilot, but involved multiple, official reports by airport officials, air traffic controllers, law enforcement, regulatory agencies, aviation investigators, and MULTIPLE pilots - reporting in detail on an extended incident that could have caused a crash during the most crucial part of two separate commercial, passenger flights.

==========
Or note that crashes have been caused by OTHER sudden bursts of bright light, where the pilots involved were not incompetent, or novices. Flashblindness, loss of spatial orientation, temporary disorientation, etc., are cited as contributing to fatal and non-fatal accidents in case after documented case.
This is not based on "anecdotal" evidence, but competent, professional, detailed review by, e.g., the NTSB, which I presume you would consider a reliable and scientific source, if in fact you bother to read their actual reports, which are excellent.
A number of studies have collated and/or summarized this data - I cite only one for brevity, a review of NTSB and FAA accident reports, which states, in part:
"There were 58 reported mishaps that identified vision problems at night resulting from exposure to sources of bright light as a contribut- ing factor in the accident (n=30) or incident (n=28). The majority of accidents (n=17) occurred during the approach and landing phase of flight. Incidents occurred most frequently while taxiing (n=15) and during approach and landing (n=10)."
These are, in the main, NOT laser-related - nonetheless, the majority occur when aircraft are flying very low, or on the ground, precisely where a laser pointer will be at greatest strength and where an aircraft is at its most vulnerable, i.e., having the least amount of time to recover from even a brief distraction.
Included is extensive discussion of why this is a genuine PHYSIOLOGICAL issue, NOT a reflection of the pilot's competence or lack thereof. See:

==========
If you are interested in truly "scientific" inquiry, you might look into the military's research into dangers of night flying and primary causes of crashes, in both training and combat missions. Distraction is always a danger, regardless of the source. Distractions at crucial moments, when there is insufficient time to recover, can trip up the most expert pilots.
===========
Or you might try a PubMed search, which will turn up several papers discussing macular damage from green laser pointers - which I point out less in response to you, by the way, and more in response to some truly idiotic commenters, who tried to claim you could stare directly into a laser pointer for short periods without harm.
This might have been true with lower powered red lasers, and indeed, several studies determined standard, correctly manufactured red laser pointers were unlikely to cause permanent harm.
But doing this with a green laser has resulted in several cases of permanent, irreversible macular damage.
(too many citations to post here, but happy to oblige in another post if requested).
===========
And last: I have not even begun to cite studies done in countries other than the United States.
I leave that research to your fine, logical, scientific mind, which should therefore include a spirit of genuine enquiry and a desire for knowledge.
