I am looking for a word, and I'm not sure if it exists. Looking for college level words here. Ostensible - Believable, but shows signs of being false. Specious - Believable, but false. Spurious - Plausible, but false. The connotation is that it is based on bad reasoning. ______? - Possible, but based on bad reasoning. I'm looking at connotations here. I think one or two of these can be stretched to mean what I want it to, but I'm thinking there is an unmistakable word I don't see. I hesitate to bring context, but I'll do for clarity. Some political candidates make statements that are possible, but the claims made are done so based on horrible reasoning. Like saying evolution exists because your best friend Johny told you so, vs looking at the mountain of research conducted by scientist.
