You reason about conditional relations because much of your knowledge is conditional. If you get caught speeding, then you pay a fine. If you have an operation, then you need time to recuperate. If you have money in the bank, then you can cash a check. Conditional reasoning is a central part of thinking, yet people do not always reason correctly. The lawyer Jan Schlictmann in a celebrated trial (see Harr, 1995, pp. 361–362) elicited the following information from an expert witness about the… 
What is wrong with false-link conditionals?
Abstract It is a common intuition that the antecedent of an indicative conditional should have something to do with its consequent, that they should be somehow connected. In fact, many conditionals
Pragmatics, Mental Models and One Paradox of the Material Conditional
TLDR
This work identifies two joint conditions under which the inference ‘y, y’ becomes acceptable: (a) the truth of x has bearings on the relevance of asserting y; and (b) the speaker can reasonably be expected not to be in a position to assume that x is false.

The mental model theory of free choice permissions and paradoxical disjunctive inferences
ABSTRACT Inferences of the sort: A or B; therefore A, are invalid. Yet, the paradoxes of free choice are acceptable: You can have sole or lobster; so, you can have sole. Pragmatic theories attempt
Specificity effects in reasoning with counterintuitive and arbitrary conditionals
TLDR
This work varied the specificity of counterintuitive conditionals, which described the opposite of what is expected according to everyday experiences and gave higher acceptance ratings for specific than for unspecific conditionals.
The Puzzle of Conditionals with True Clauses: Against the Gricean Account
TLDR
An experimental study investigating how the presence or absence of a connection between the clauses affects the assertability of conditionals and conjunction expressing generic and specific kind of content refutes the standard pragmatic explanation.
A Priori True and False Conditionals.
TLDR
Three experiments corroborated the model theory that certain conditionals should be true or false without the need for evidence and considered the implications for theories of reasoning based on logic, probabilistic logic, and suppositions.
The Relation Between Factual and Counterfactual Conditionals
TLDR
Two experiments supported the theory of mental models and its computer implementation that both can have a priori truth values and that the semantic bases of both are possibilities: states that are possible for factual conditionals, and that were once possible but that did not happen for counterfactual conditionals.
Reasoning with Exceptive Conditionals: The case of ‘Except If’
In this paper we outline a mental model theory (Johnson-Laird & Byrne, 1991, 2002) of reasoning about the conditional except if. We report two experiments showing that the exceptive conditional

TLDR
It is argued that the subjects did not give evidence of having acquired the characteristics of Piaget's “formal operational thought,” and it is suggested that the difficulty is due to a mental set for expecting a relation of truth, correspondence, or match to hold between sentences and states of affairs.

TLDR
Reasoners who made a counterfactual interpretation of subjunctive statements endorsed different inferences than those who did not and were more likely to judge the situation in which p and q occurred to be inconsistent with the conditional statement and make negative inferences such as modus tollens.
Reasoning about Conditional Promises and Warnings: Darwinian Algorithms, Mental Models, Relevance Judgements or Pragmatic Schemas?
