MUFON uses a report evaluation procedure developed by Vicente-
Juan Ballester Olmos and Miguel Guasp. Part of the evaluation is
'Witness Reliability' and one of its sections deals with witness

Each age group is given a weight and this weight is evaluated as
10% of the overall witness reliability rating.

0.0 - unknown
0.2 - under 10 years
0.4 - between 10 and 17 years
0.6 - between 18 and 34 years
0.8 - between 65 and 74 years
1.0 - between 35 and 64 years
0.2 - over 75 years

You might notice that those over 75 are given the same weight as
a child under 10.

With all this, however, witness age is only one of the factors
involved with the reliability of the witness.  Occupation and
activity at time of the event are among the other factors.

For example, without going in to mathematical detail, a single
witness over age 75, retired military, on vacation (at time of
sighting) would be given a reliability rating of 55.1%. This is
still a respectable rating. If they were at a cultural event or
at work the rating would go even higher.

Of course much of this is subjective, but still, age should
never be the only factor when weighing a person's reliability as
a witness.
