These "journals" are "published" on the net. This makes it quite easy to look for the sponsoring professional society or university or the editorial board. If none of these is mentioned anywhere, the red lights should start flashing. If one or more of these appear, go and do some research on it.
I guess we have to look at all of them. Professional association (sponsorship, etc.) and editorial board. And checked. If these are not provided, those red lights should be acompanied by a very loud siren.
I don't really think that many people on the street would even try to look at a scientific journal anyway. Lots of people on the street think that National Geographic is a scientific journal. That won't change quickly.
What matters would be the people who do know something about science. They won't be fooled that easily.
Oh, they most definitely will. I won't be surprised if most of those 'journals' were started by creationist groups for the sole purpose of pretending that they publish 'research'
I mean, we had such an example for some time (seems like it's dead now). The 'Journal' called BIO-Complexity, basically an in-house religious tract for the DI, published by the "Biologic Institute". Boy, do they always reference that propaganda as scientific articles.
