TWO HYPOTHETICAL CASES INVOLVING ROBBERY AND BURGLARY WER USED FOR A DECISIONMAKING SIMULATION (BASED ON THE WILKIN TECHNIQUE). THE SAMPLE INCLUDED 136 PROSECUTORS AND 104 DEFENSE ATTORNEYS ACROSS THE STATES. WITHIN THE SIMULATIO A QUASI-EXPERIMENTAL DESIGN WAS USED TO MANIPULATE THE VARIABLES OF THE DEFENDANT'S PRIOR RECORD AND THE STRENGT OF THE CASE. IN ADDITION, PROSECUTORS WERE ASKED FOR THE LOWEST SENTENCE RECOMMENDATION THEY WOULD MAKE TO THE DEFENSE, AND DEFENSE ATTORNEYS WERE ASKED FOR THEIR HIGHEST RECOMMENDATION. FINALLY, AN ESTIMATE WAS REQUESTE REGARDING THE PROBABILITY OF CONVICTION IN THE CASES. FINDINGS SHOWED THAT BOTH PROSECUTORS AND DEFENSE ATTORNEYS EXAMINE THE BASIC FACTS, PRIOR RECORD, AND STRENGTH OF EACH CASE, ALL FACTORS WHICH WERE CONFIRMED A THE MOST IMPORTANT UNITS OF INFORMATION. HOWEVER, DEFENSE ATTORNEYS TEND TO LOOK AT MORE UNITS OF INFORMATION, ESPECIALLY THAT WHICH IS DESCRIPTIVE OF DEFENDANTS' CHARCTERISITCS. IN TERMS OF THE CASE DISPOSITION DECISION, DEFENSE COUNSEL SELECTED A GREATER NUMBER OF INFORMATION UNITS; YET THE LENGTH AND TYPE OF ATTORNEYS' EXPERIENCE HAD NO IMPACT ON THE AMOUNT OF INFORMATION SELECTED. ESTIMATES OF CONVICTION PROBABILITY WERE THE SAME FOR BOTH GROUPS FOR THE BURGLARY CASE, BUT HIGHER FOR PROSECUTORS IN THE ROBBERY CASE. STRENGTH OF EVIDENCE HAD THE GREATEST IMPACT ON THE ESTIMATE OF CONVICTION PROBABILITY. PROSECUTORS WERE MORE LIKELY TO ENGAGE IN PLEA NEGOTIATIONS, WITH STRONG EVIDENCE AND LONG RECORDS INCREASING THE PROBABILITY OF NEGOTIATION. PROSECUTORS PRESSED FOR MORE SEVERE SENTENCES. PRIOR RECORD WAS IMPORTANT FOR BOTH BURGLARY AND ROBBERY, BUT EVIDENCE WAS AN IMPORTANT FACTOR IN BURGLARY ONLY. PERHAPS THE SERIOUSNESS OF THE ROBBERY CASE OUTWEIGHS THE IMPACT OF EVIDENCE, WHILE FOR THE BURGLARY CASE, A SMALL BUT NOTICEABLE EFFECT REGARDING CONVICTION PROBABILITY APPEARED. NOTES ARE INCLUDED, ALONG WITH TABLES OF RESPONSES. APPENDIXES PRESENT THE SIMULATION TOOLS. (MHP)
